2. clear bgp external
3. clear bgp *
DETAILED STEPS
Displaying System and Network Statistics
Perform this task to display specific statistics, such as the contents of BGP routing tables, caches, and
databases. Information provided can be used to determine resource usage and solve network problems.
You can also display information about node reachability and discover the routing path that the packets
of your device are taking through the network.
SUMMARY STEPS
1. show bgp cidr-only
2. show bgp count-only
3. show bgp community community-list [exact-match]
4. show bgp regexp regular-expression
5. show bgp
6. show bgp neighbors ip-address [advertised-routes | dampened-routes | flap-statistics |
performance-statistics | received prefix-filter | routes]
7. show bgp paths
