30 Displaying BGP4 information TABLE 187 BGP4 route summary information for a neighbor Field Description Routes Received How many routes the Layer 3 Switch has received from the neighbor during the current BGP4 session: • Accepted/Installed - Indicates how many of the received routes the Layer 3 Switch accepted and installed in the BGP4 route table. • Filtered - Indicates how many of the received routes the Layer 3 Switch did not accept or install because they were denied by filters on the Layer 3 Switch. Routes Selected as BEST Routes The number of routes that the Layer 3 Switch selected as the best routes to their destinations. BEST Routes not Installed in IP Forwarding Table The number of routes received from the neighbor that are the best BGP4 routes to their destinations, but were nonetheless not installed in the IP route table because the Layer 3 Switch received better routes from other sources (such as OSPF, RIP, or static IP routes). Unreachable Routes The number of routes received from the neighbor that are unreachable because the Layer 3 Switch does not have a valid RIP, OSPF, or static route to the next hop. History Routes The number of routes that are down but are being retained for route flap dampening purposes. NLRIs Received in Update Message The number of routes received in Network Layer Reachability (NLRI) format in UPDATE messages: • Withdraws - The number of withdrawn routes the Layer 3 Switch has received. • Replacements - The number of replacement routes the Layer 3 Switch has received. NLRIs Discarded due to Indicates the number of times the Layer 3 Switch discarded an NLRI for the neighbor due to the following reasons: • Maximum Prefix Limit - The Layer 3 Switch configured maximum prefix amount had been reached. • AS Loop - An AS loop occurred. An AS loop occurs when the BGP4 AS-path attribute contains the local AS number. • Invalid Nexthop - The next hop value was not acceptable. • Duplicated Originator_ID - The originator ID was the same as the local router ID. • Cluster_ID - The cluster list contained the local cluster ID, or contained the local router ID (see above) if the cluster ID is not configured. Routes Advertised The number of routes the Layer 3 Switch has advertised to this neighbor: • To be Sent - The number of routes the Layer 3 Switch has queued to send to this neighbor. • To be Withdrawn - The number of NLRIs for withdrawing routes the Layer 3 Switch has queued up to send to this neighbor in UPDATE messages. 1076 PowerConnect B-Series FCX Configuration Guide 53-1002266-01
