If that colum is showing “Active” or “Idle”, it means bgp peering has not been completed. In the above output, the last column State/PfxRcd is used to understand the status of BGP peering, if it set to a number (0 or more), it means peering has been established and that value shows how many networks has been learned from that peer. Show ip bgp summary can be used check how many neighbors are added, status of the peering and the number of routes received from each neighbor. In the above output origin code is “i” meaning that the network is originally advertised by a bgp speaking router connected to that network The symbol at the end of line shows the origin code.

This column shows the value of AS-PATH attribute. Weight is set to 32768 by default for all local networks and will be 0 for ibgp and ebgp routes Local preference will be by default 100 for routes learned from ibgp peers. Local preference attribute is not applicable for ebgp peering, so this column is not populated in this scenario. This column shows the value of MED attribute, by default MED is set to 0 In the above output R1 has set NOH as 0.0.0.0 for the connected network 10.0.0.0 If the Next Hop column is set 0.0.0.0, it shows that this network is directly connected one.

Status code will be “*>i” if it is a route learned from ibgp peer.

“>” shows that this path is the best path to reachable destination. The status code will show “*” if a route is a valid one and the NOH is reachable. In the above output you can see two networks (10.0.0.0 and 20.0.0.0) in bgp table.
