Command introduced before JUNOSe Release
7.1.0. ipv6Address variable added
in JUNOSe Release 8.0.0.
Description
Controls advertisement of BGP capabilities to peers.
Capability negotiation and advertisement of all capabilities, except
the ORF capability, is enabled by default. The no version disables capability negotiation or prevents advertisement
of the specified capability. The default version restores the default condition, advertising the capability.
Options
ipAddress—IP address of BGP
neighbor
ipv6Address—IPv6 address of
BGP neighbor; because IPv6 ORF prefix lists are not supported, this
variable is valid for the ORF c capability only under the IPv4 address
family for advertising IPv4 routes over BGP IPv6 peers
peerGroupName—Name of BGP
peer group. If you specify a BGP peer group by using the peerGroupName argument, all the members of the peer group
inherit the characteristic configured with this command, unless it
is overridden for a specific peer.
negotiation—Determines whether the capabilities
option is sent in the open message while establishing a session; if
it is not sent, no capability negotiation is conducted with that peer
deprecated-dynamic-capability-negotiation—Indicates
support of negotiation of capabilities (sending new capabilities or
removing previously negotiated capabilities) without performing a
hard clear of the BGP session; the capability data field does not
include a list of capabilities that can be dynamically negotiated
dynamic-capability-negotiation—Indicates support
of negotiation of capabilities (sending new capabilities or removing
previously negotiated capabilities) without performing a hard clear
of the BGP session; the capability data field includes a list of capabilities
that can be dynamically negotiated
four-octet-as-numbers—Indicates support of AS numbers
and sub-AS numbers that are four octets in length, in the range 0–4294967295
route-refresh—Indicates support of route-refresh
messages that request the peer to resend its routes to the router,
enabling the BGP speaker to apply modified or new policies to the
routes when it receives them again
route-refresh-cisco—Indicates support of Cisco-proprietary
(prestandard) route-refresh messages for interoperability with older
Cisco devices
orf—Indicates support of cooperative route filtering
to install a BGP speaker’s inbound route filter as an outbound
route filter on the peer
prefix-list—Installs the filter (any inbound prefix
list or distribute list) as an outbound prefix list
prefix-list-cisco—Installs the filter (any inbound
prefix list or distribute list) as an outbound Cisco proprietary prefix
list
send—Sends inbound route filter to the peer to install
as the outbound route filter
receive—Accepts inbound route filter from the peer
and installs it as the outbound route filter; cannot be configured
for a peer group or a peer that is a member of a peer groups
both—Sends and accepts inbound route filters with
the peer for installation as the outbound route filter
