BGP. Realizar peering eBGP usando Arista.

[HECTORCHIMAL]

OPCIONAL

Podemos crear filtros para garantizar que nuestro carrier solo nos anunciará la ruta por defecto y que nosotros solo anunciaremos el nuestro.

1 Crear prefix-list

!

ipv6 prefix-list IPv6-Ruta-Default

   seq 10 permit ::/0

!

ipv6 prefix-list Mi-Prefijo-IPv6

   seq 10 permit 2806:3e6::/32

!

2 Crear route-maps

!

route-map IN-eBGP-peer-Carrier permit 10

   match ipv6 address prefix-list IPv6-Ruta-Default

!

route-map OUT-eBGP-peer-Carrier permit 10

   match ipv6 address prefix-list Mi-Prefijo-IPv6

!

3 Asociar nuestros route-map a nuestro peer (nuestro carrier)

!

router bgp 270159

   address-family ipv6
neighbor 2806:3f7:1002:aaaa::f0ca:f0ca route-map IN-eBGP-peer-Carrier in
neighbor 2806:3f7:1002:aaaa::f0ca:f0ca route-map OUT-eBGP-peer-Carrier out
