Optionally, you can specify an IP address in order to display only that particular neighbor. In this mode, you can optionally specify whether you want to display all routes advertised to the specified neighbor, all routes received from the specified neighbor or all routes (received and accepted) from the specified neighbor.
Example:

admin@sonic:~$ show bgp neighbors 192.168.1.161

admin@sonic:~$ show bgp neighbors 192.168.1.161 advertised-routes

admin@sonic:~$ show bgp neighbors 192.168.1.161 received-routes

admin@sonic:~$ show bgp neighbors 192.168.1.161 routes

show ipv6 bgp neighbors <ipv6-address> (advertised-routes | received-routes | routes)
- Displays details of IPv6 Border Gateway Protocol (BGP) neighbors
- In this mode, you must specify the IPv6 address of a neighbor and choose whether you want to display all routes advertised to the specified neighbor, all routes received from the specified neighbor or all received and accepted routes from the specified neighbor.
- Example:
```
admin@sonic:~$ show ipv6 bgp neighbors fc00::72 advertised-routes

admin@sonic:~$ show ipv6 bgp neighbors fc00::72 received-routes

admin@sonic:~$ show ipv6 bgp neighbors fc00::72 routes
