ToR2(config-router-neighbor)# no shutdown
ToR2(config-router-neighbor)# exit
Debug BGP
Use the following procedure to debug BGP.
● To debug BGP:
debug ip bgp
BGP commands
activate
Enables the neighbor or peer group to be the current address-family identifier (AFI).
Syntax
activate
Parameters None
Default Not configured
Command Mode ROUTER-BGP-NEIGHBOR-AF
Usage
Information
This command exchanges IPv4 or IPv6 address family information with an IPv4, IPv6, and L2VPN
neighbor. IPv4 unicast Address family is enabled by default. To activate IPv6 address family for IPv6
neighbor, use the activate command. To deactivate IPv4 address family for IPv6 neighbor, use the no
