Debug BGP
Use the following procedure to debug BGP.
● To debug BGP:
debug ip bgp
Configuring BGP template
Configure the BGP templates to support the following attributes in IPv4 and IPv6 address family level: next-hop-self, oft-
reconfiguration inbound, maximum-prefix, and add-path.
To configure BGP template:
1. Configure peer-group under BGP.
OS10(config)# router bgp 100
OS10(config-router-bgp-100)# template abc
2. Configure maximum-prefix in IPV4 AFI, where maximum-prefix is 10, threshold is 50, and warning is enabled.
OS10(config-router-template)# address-family ipv4 unicast
OS10(config-router-bgp-template-af)# maximum-prefix 10 50 warning-only
