Hello All,
I am trying to configure IPV6 BGP between two directly connected routers, but am not able to ping directly connected interfaces and of course BGP neighborship is also not establishing. Configuration is mentioned for your feedback.
R1 configuration
interface GigabitEthernet0/0
ip address 192.168.1.1 255.255.255.0
ipv6 address 2000:CC13:CC13:CC13::1/128
end
interface Loopback0
ip address 1.1.1.1 255.255.255.255
ipv6 address 2000:CC13:CC13:1::1/128
end
router bgp 65515
