Re: Internet routes, Global Routing table or VRF

Helo Peter,

my 0.02$

Internet in Global Routing

Pro:

- Wellknown configs and behaviour

- separate address-family (separate route refresh, etc.)

- potentially separate RR for internet

- usual memory consumption

Con:

- larger Global Routing table

Internet in VRF

Pro:

- smaller global routing table

- more (useless?) features like as-override

Con:

- more memory consumption (RD, RTs)

- higher operational risk ("route-target import" could copy internet table into customer VPN)

- more difficult operation (one BGP table, harder to find VPN customer routes)

So guess what: I would have the internet in the global routing table.

Hope this helps! Please rate all posts.

Regards, Martin
