Monitoring BGP Next Hops
Purpose
Display information about all indirect next hops or a particular next hop.
The show ip bgp next-hops and show bgp ipv6 next-hops commands display similar information.
Action
To display information about all indirect next hops or a particular indirect next hop:
host1#show ip bgp next-hops

Reachable (metric 2)
Direct next-hop atm2/0.34 (34.34.34.4)
Reference count is 3
Indirect next-hop ::ffff:2.2.2.2
MPLS stacked label 17
Reachable (metric 3)
Direct next-hop tun mpls:vpnInL17-23
Reference count is 1
Indirect next-hop 5.5.5.5
Reachable (metric 2)
Direct next-hop atm2/0.35 (35.35.35.5)
Reference count is 3
Indirect next-hop 6.6.6.6
Reachable (metric 3)
Direct next-hop atm2/0.34 (34.34.34.4)
atm2/0.35 (35.35.35.5)
Reference count is 3

Table 1 lists the show ip bgp next-hops command output fields.
Table 1: show ip bgp next-hops Output Fields
Field Name | Field Description |
|---|---|
Indirect next-hop | BGP next-hop attribute as received in the BGP update message |
Reachable | Indicates whether or not the indirect next hop is reachable. |
Metric | Metric of the BGP indirect next hop |
Direct next-hop | IP interface and next-hop IP address that resolve the BGP indirect next hop; the direct next hop can also be an IP indirect next hop or an MPLS indirect next hop when chains of next hops are in use |
Reference count | Number of label mappings of BGP routes that use this next hop |
