Setting Multicast Bandwidths

You can use the set admission-bandwidth command to set a multicast bandwidth for admission control. Admission control is performed for the join and mapped interface when the OIF is added to the mroute.

You can use the set qos-bandwidth command to set a multicast bandwidth for QoS control. The QoS adjustment is made to the join interface when the OIF is added to the mroute.

Note: Both the admission bandwidth and QoS bandwidth are a constant bit rate.

For more information about multicast admission control or QoS adjustment, see Configuring IPv4 Multicast or chapter Configuring IPv6 Multicast in JUNOSe Multicast Routing Configuration Guide.

match as-path

match distance

• Use to match any routes being redistributed out of the routing table that have the specified administrative distance.
• Distance is used to determine the relative preference between routes to the same prefix in order to pick the best route to that prefix in the routing table. Distance has no meaning in any other circumstance, and any attempt to match distance fails.
• Example

  host1(config-route-map)#match distance 25

• Use the no version to delete the match clause from a route map or a specified value from the match clause.
• See match distance.

match extcommunity

• Use to match an extended community list in a route map.
• You can specify one or more extended community list names in a match clause. If you specify more than one extended community list, the lists are logically ORed.
• Example

  host1(config-route-map)#match extcommunity topeka10

• Use the no version to remove the match clause from a route map or a specified value from the match clause.
• See match extcommunity.

match ip address

• Use the no version to delete the match clause from a route map or a specified value from the match clause.
• See match ip next-hop.

match ipv6 address

• Use to match any routes that have a destination network number address that is permitted by the specified prefix list.
• Example

  host1(config-route-map)#match ipv6 address prefix-list boston

• Use the no version to delete all address match clauses from a route map unless you specify a prefix list, in which case only that prefix list match is removed from the route map.
• See match ipv6 address.

match ipv6 next-hop

• Use to match any routes that have a next-hop router address passed by the specified prefix list.
• Example

  host1(config-route-map)#match ipv6 next-hop prefix-list next1

  host1(config-route-map)#match tag 25

• Use the no version to delete the match clause from a route map or a specified value from the match clause.
• See match tag.

route-map

• Use to define the conditions for redistributing routes from one routing protocol to another, and for filtering or modifying updates sent to or received from peers.
• Each route-map command has a list of match and set commands associated with it. That is, the route map itself consists of a set of clauses; each clause (also called an entry) consists of a match or set command:
  • match commands specify the match criteria, the conditions under which redistribution is allowed for the current route map.
  • set commands specify the set actions, the redistribution actions to perform if the criteria enforced by the match commands is met.
• You can specify match and set clauses to modify attributes of redistributed routes.
• Use route maps when you want to have detailed control over how routes are redistributed between routing processes.
  • You specify the destination routing protocol with the router command.
  • You specify the source routing protocol with the redistribute command.
• Example

  host1(config)#route-map nyc1 permit 10

  host1(config-route-map)#match ip address list1

  host1(config-route-map)#set metric-type internal

• Use the no version to delete the route map.
• See route-map.

set as-path prepend

• Use to modify an AS path for BGP routes by prepending one or more AS numbers or a list of AS numbers to the path list.
• The only global BGP metric available to influence the best path selection is the AS path length. By varying the length of the AS path, a BGP device can influence the best path selection by a peer farther away.
• Example

  host1(config-route-map)#set as-path prepend list list10

• Use the no version to delete the set clause from a route map.
• See set as-path prepend.

set automatic-tag

• Use to automatically compute the tag value of the destination routing protocol.
• Example

  host1(config-route-map)#set automatic-tag

• Use the no version to delete the set clause from a route map.
• See set automatic-tag.

set comm-list delete

• Use to remove communities specified by the community list from the community attribute of routes that match the route map.
• You can use this command to delete communities only if the community list was created with a single community per list entry, as the following sample configuration for router host1 shows:

  host1(config)#ip community-list 1 permit 231:10

  host1(config)#ip community-list 1 permit 231:20

  host1(config)#router bgp 45

  host1(config-router)#neighbor 10.6.2.5 remote-as 5

  host1(config-router)#neighbor 10.6.2.5 route-map indelete in

  host1(config-router)#route-map indelete permit 10

  host1(config-route-map)#set comm-list 1 delete

  Router host1 receives the same route from 10.6.2.5 and applies the indelete route map. BGP compares each list entry with the community attribute. A match is found for the list entry 231:10, and this community is deleted from the community attribute. Similarly, a match is found for the list entry of 231:20, and this community is deleted from the community attribute.

• Example

  host1(config-route-map)#set comm-list 1 delete

• Use the no version to delete the set clause from a route map.
• See set comm-list delete.

set community

• Use to set the community attribute in BGP updates.
• You can specify a community list number in the range 1–4294967295, or in the new community format of AA:NN, or one of the following well-known communities:
  • local-asr—Prevents advertisement outside the local AS
  • no-advertise—Prevents advertisement to any peer
  • no-export—Prevents advertisement beyond the BGP confederation boundary
• Alternatively, you can use the list keyword to specify the name of a community list that you previously created with the ip community-list command.
• Example

  host1(config-route-map)#set community no-advertise

• Use the none keyword to remove the community attribute from a route.
• Use the no version to delete the set clause from a route map.
• See set community.

set dampening

• Use to enable BGP route flap dampening only on routes that pass the match clauses of, and are redistributed by, a particular route map.
• BGP creates a dampening parameter block for each unique set of dampening parameters—such as suppress threshold, reuse threshold, and so on—used by BGP. For example, if you have a route map that sets the dampening parameters to one set of values for some routes and to another set of values for the remaining routes, BGP uses and stores two dampening parameter blocks, one for each set.
• Example

  host1(config-route-map)#set dampening 5 1000 1500 45 15

• Use the no version to delete the set clause from a route map.
• See set dampening.

set distance

• Use to set the administrative distance on routes being installed into the routing table that match the route map.
• Distance establishes preference between routes to the same prefix to identify the best route to that prefix. Setting distance in any other circumstance has no effect.
• Example

  host1(config-route-map)#set distance 5

• Use the no version to delete the set clause from a route map.
• See set distance.

set extcommunity

• Use to set the extended community attributes in a route map for BGP updates.
• You can specify a site-of-origin (soo) extended community and a route target (rt) extended community at the same time in a set clause without overwriting the other.
• Example

  host1(config-route-map)#set extcommunity rt 10.10.10.2:325

• Use the no version to delete the set clause from a route map.
• See set extcommunity.

set ip next-hop

• Use to set the next hop attribute of a route that matches a route map.
• You can specify an IP address or an interface as the next hop.
• Use the peer-address keyword to have the following effect:
  • On outbound route maps, disables the next-hop calculation by setting the next hop to the IP address of the BGP device
  • On inbound route maps, overrides any third-party next-hop configuration by setting the next hop to the IP address of the peer
• Example

  host1(config-route-map)#set ip next-hop 192.56.32.1

• Use the no version to delete the set clause from a route map.
• See set ip next-hop.

set ipv6 next-hop

• Use to set the next hop attribute of a route that matches a route map.
• You can specify an IPv6 address or an interface as the next hop.
• Example

  host1(config-route-map)#set ipv6 next-hop 1::1

• Use the no version to delete the set clause from a route map.
• See set ipv6 next-hop.

set level

• Use to specify where to import routes when all of a route map's match criteria are met.
• Example

  host1(config-route-map)#set level level-2

• Use the no version to delete the set clause from a route map.
• See set level.

set local-preference

• Use to specify a preference value for the AS path.
• Example

  host1(config-route-map)#set local-preference 200

• Use the no version to delete the set clause from a route map.
• See set local-preference.

set metric

• Use to set the metric value (for BGP, the MED) for a route.
• To establish an absolute metric, do not enter a plus or minus sign before the metric value.
• Example

  host1(config-route-map)#set metric 10

• To establish a relative metric, specify a plus or minus sign immediately preceding the metric value. The value is added to or subtracted from the metric of any routes matching the route map. The relative metric value range is 0–4294967295.
• Example

  host1(config-route-map)#set metric -25

• You cannot use both an absolute metric and a relative metric within the same route map sequence. Setting either metric overrides any previously configured value.
• Use the no version to delete the set clause from a route map.
• See set metric.

set metric-type

• Use to set the metric type for a route.
• For BGP, this command affects BGP behavior only in outbound route maps and has no effect on other types of route maps. If the route map contains both a set metric-type and a set metric clause, the set metric clause takes precedence. If you specify the internal metric type in a BGP outbound route map, BGP sets the MED of the advertised routes to the IGP cost of the next hop of the advertised route. If the cost of the next hop changes, BGP is not forced to readvertise the route.
• For BGP, you can specify the following metrics:
  • external—Reverts to the normal BGP rules for propagating the MED; this is the BGP default
  • internal—Sets the MED of a received route that is being propagated to an external peer equal to the IGP cost of the indirect next hop
• For IS-IS, you can specify the following metrics:
  • external—Considers only the metric of the route itself is considered for comparison
  • internal—Considers both the metric of the route and the cost to the router that advertised the route are considered for comparison; this is the IS-IS default
• For OSPF, you can specify the following metrics:
  • 1—Sets the cost of the external routes so that it is equal to the sum of all internal costs and the external cost
  • 2—Sets the cost of the external routes so that it is equal to the external cost alone; this is the OSPF default
• Example

  host1(config-route-map)#set metric-type internal

• Use the no version to delete the set clause from a route map.
• See set metric-type.

set origin

• Use to set the BGP origin of the advertised route.
• Example

  host1(config-route-map)#set origin egp

• Use the no version to delete the set clause from a route map.
• See set origin.

set route-class

• Use to set the route class value. The route-class attribute enables you to associate a route class with incoming packets based on the destination or source address of the packet. For example, you can associate different route classes with different VPN services, while using the route classes to classify packets for quality of service (QoS).
• Example

  host1(config-route-map)#set route-class 50

• Use the no version to delete the set clause from a route map.
• See set route-class.

set route-type

• Use to set the routes of the specified type (internal, internal-intra, internal-inter, or external).
• Example

  host1(config-route-map)#set route-type internal

• Use the no version to delete the set clause from a route map.
• See set route-type.

set tag

• Use to set the tag value of the destination routing protocol.
• Example

  host1(config-route-map)#set tag 23

• Use the no version to delete the set clause from a route map.
• See set tag.

set weight

• Use to specify the BGP weight for the routing table.
• The weights assigned with the set weight command in a route map override the weights assigned using the neighbor weight and neighbor filter-list weight commands.
• Example

  host1(config-route-map)#set weight 200

• Use the no version to delete the set clause from a route map.
• See set weight.
