show ip bgp ipv6 unicast neighbors

Displays information on IPv6 unicast routes exchanged by BGP neighbors.

Syntax show ip bgp ipv6 unicast neighbors [ ipv4-neighbor-addr | ipv6-neighbor-addr] [advertised-routes | dampened-routes | detail | flap-statistics | routes | received-routes [ network [ network-mask]] | denied-routes [ network [ network-mask]]]
Parameters
ipv6 unicast Enter the keywords ipv6 unicast to view information only related to IPv6 unicast routes.
ipv4-neighbor-addr | ipv6-neighbor-addr (OPTIONAL) Enter the IP address of the neighbor to view only BGP route information exchanged with that neighbor.
advertised-routes (OPTIONAL) Enter the keywords advertised-routes to view only the routes the neighbor sent.
dampened-routes (OPTIONAL) Enter the keywords dampened-routes to view information on dampened routes from the BGP neighbor.
detail (OPTIONAL) Enter the keyword detail to view neighbor-specific internal information for the IPv4 Unicast address family.
flap-statistics (OPTIONAL) Enter the keywords flap-statistics to view flap statistics on the neighbor’s routes.
routes (OPTIONAL) Enter the keyword routes to view only the neighbor’s feasible routes.
received-routes [ network [ network-mask] (OPTIONAL) Enter the keywords received-routes then either the network address (in dotted decimal format) or the network mask (in slash prefix format) to view all information received from neighbors.
  • NOTE: You must configure the neighbor soft-reconfiguration inbound command prior to viewing all the information received from the neighbors.
denied-routes [ network [ network-mask] (OPTIONAL) Enter the keywords denied-routes then either the network address (in dotted decimal format) or the network mask (in slash prefix format) to view all information on routes denied using neighbor inbound filters.

Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information The following describes the show ip bgp ipv6 unicast neighbors command shown in the Example below.
Lines Beginning With Description
BGP neighbor Displays the BGP neighbor address and its AS number. The last phrase in the line indicates whether the link between the BGP router and its neighbor is an external or internal one. If they are located in the same AS, then the link is internal; otherwise, the link is external.
BGP version Displays the BGP version (always version 4) and the remote router ID.
BGP state Displays the neighbor’s BGP state and the amount of time in hours:minutes:seconds it has been in that state.
Last read This line displays the following information:
  • last read is the time (hours:minutes:seconds) the router reads a message from its neighbor
  • hold time is the number of seconds configured between messages from its neighbor
  • keepalive interval is the number of seconds between keepalive messages to help ensure that the TCP session is still alive
Received messages This line displays the number of BGP messages received, the number of notifications (error messages), and the number of messages waiting in a queue for processing.
Sent messages The line displays the number of BGP messages sent, the number of notifications (error messages), and the number of messages waiting in a queue for processing.
Received updates This line displays the number of BGP updates received and sent.
Soft reconfiguration This line indicates that soft reconfiguration inbound is configured.
Minimum time Displays the minimum time, in seconds, between advertisements.
(List of inbound and outbound policies) Displays the policy commands configured and the names of the Route map, AS-PATH ACL, or Prefix list configured for the policy.
For address family: Displays IPv6 Unicast as the address family.
BGP table version Displays which version of the primary BGP routing table the router and the neighbor are using.
Prefixes accepted Displays the number of network prefixes accepted by the router and the amount of memory used to process those prefixes.
Prefixes advertised Displays the number of network prefixes advertised, the number rejected, and the number withdrawn from the BGP routing table.
Connections established Displays the number of TCP connections established and dropped between the two peers to exchange BGP information.
Last reset Displays the amount of time since the peering session was last reset. Also states if the peer resets the peering session. If the peering session was never reset, the word “never” is displayed.
Local host: Displays the peering address of the local router and the TCP port number.
Foreign host: Displays the peering address of the neighbor and the TCP port number.
