provides Border Gateway Protocol (BGP) peering status for an ION
device at a branch site or a data center. It includes information
on BGP peer types, including classic, core, and edge peers depending
on the type of site, namely a branch or a data center.
In addition, it displays information on the BGP
peering state and advertised and reachable prefixes. While the classic
and core peers display advertised and reachable prefixes, the edge
peer will display only reachable prefixes. Reachable prefixes are
prefixes that the ION device learns from the peer, whereas advertised
prefixes are prefixes that the ION device advertises to the classic and
You may filter individual routes or prefixes from received and
advertised prefixes along with network, Autonomous System (AS) path,
and next-hop information. From advertised, reachable, or discoverable
prefixes, you can search for specific routes or prefixes.
Use routing to troubleshoot BGP connections and check if routes
are learned from or advertised to the BGP peers. For example, you
can verify whether a peer is connected by checking the peer's BGP
state. If the peer is not connected, the State field will provide information
on the peer's status, dropped connections, duration of BGP peer
uptime and downtime, and notifications. If any prefix id is not
reachable, check if the route is learned from the WAN edge or is
advertised to the core or classic peer.
