SUMMARY STEPS
1. configure
2. vrf vrf-name
3. address-family { ipv4 | ipv6 } unicast
4. import route-target [ as-number:nn | ip-address:nn ]
5. export route-target [ as-number:nn | ip-address:nn ]
6. interface type interface-path-id
7. vrf vrf-name
8. ipv4 address ipv4-address subnet-mask
9. dot1q native vlan vlan-id
10. router bgp as-number
11. nsr
12. bgp router-id ip-address
13. address-family {vpnv4 | vpnv6} unicast
14. neighbor ip-address
15. remote-as as-number
16. update-source type interface-path-id
17. address-family { vpnv4 | vpnv6 } unicast
18. route-policy route-policy-name in
19. route-policy route-policy-name out
20. vrf vrf-name
21. rd { as-number:nn | ip-address:nn | auto }
22. address-family { ipv4 | ipv6 } unicast
23. redistribute connected [ metric metric-value ] [ route-policy route-policy-name ]
24. redistribute static [ metric metric-value ] [ route-policy route-policy-name ]
25. neighbor ip-address
26. remote-as as-number
