show bgp ipv6 regexp

Syntax

show bgp ipv6
[ unicast | multicast | vpnv6 all | vpnv6 vrf vrfName | route-target signaling ]
regexp pathExpression [ fields { fieldOptions } ] [ filter ]

Release Information

Command introduced before JunosE Release 7.1.0.
route-target signaling keywords added in JunosE Release 8.2.0.

Description

Displays information about IPv6 BGP routes whose AS path matches one or more specified regular expressions. Regular expressions match numbers for which the specified path is a substring—for example, if you specify 20, 200 matches because 20 is a substring of 200. You can disallow substring matching by using the underscore (_) metacharacter to constrain matching to the specified pattern; for example, _20_. You can use output filtering on the display.

Options

• unicast—Specifies the IPv6 unicast address family and routing table; the default option
• multicast—Specifies the IPv6 multicast address family and routing table
• vpnv6 all—Specifies the VPN-IPv6 address family and all IPv6 VPN routing and forwarding instances
• vpn6 vrf vrfName—Specifies the VPN-IPv6 address family and only the IPv6 VPN routing and forwarding instance with the name vrfName
• route-target signaling—Specifies the route-target address family
• regexp—Indicates that multiple elements can be matched
• pathExpression—See the show ip bgp regexp command for descriptions
• fields—Displays only the specified fields; the display order of the fields is hard-coded and not affected by the order in which you enter them
• fieldOptions—Fields to be displayed, in the format
  all | [ afi | aggregator | as-path | atomic-aggregate | best | clusters | communities | extended-communities | imported | intro | in-label | loc-pref | med | next-hop | next-hop-cost | origin | originator-id | out-label | peer | peer-type | rd | safi | stale | unknown-types | weight ]*
  • all—All available information; not recommended, because this information for each network does not fit on a single line and is difficult to read
  • afi—Address family identifier
  • aggregator—AS number and IP address of aggregator
  • as-path—AS path through which this route bas been advertised
  • atomic-aggregate—Whether the atomic aggregate attribute is present
  • best—Whether this is the best route for the prefix
  • clusters—List of cluster IDs through which the route has been advertised
  • communities—Community number associated with the route
  • extended-communities—Extended community
  • imported—Whether the route was imported
  • intro—Introductory information about the state of various BGP attributes; this information is displayed only if you specify this keyword
  • in-label—MPLS label for the route; the label received with incoming MPLS frames; typically, but not always, this is the label advertised to MP-BGP peers
  • loc-pref—Local preference for the route
  • med—Multiexit discriminator for the route
  • next-hop—IP address of the next router that is used when forwarding a packet to the destination network
  • next-hop-cost—Whether the indirect next hop of the route is unreachable, if not, displays IGP cost to the indirect next hop
  • origin—Origin of the route
  • originator-id—Router ID of the router in the local AS that originated the route
  • out-label—MPLS label for the route; the label sent with outgoing MPLS frames; also the label received from MP-BGP peer; typically, but not always, this is the label received from MP-BGP peers
  • peer—IP address of BGP peer from which route was learned
  • peer-type—Type of BGP peer: internal, external, or confederation
  • rd—Route distinguisher
  • safi—Subsequent address family identifier
  • stale—Route that has gone stale due to peer restart
  • unknown-types—Attribute codes for unknown path attributes
  • weight—Weight of the route
  • *—Indicates that one or more parameters can be repeated multiple times in a list in the command line
• filter—See Filtering show Commands
