site to site routing protocol best practice

I am configuring a site to site VPN with a Cisco ASA 5510 on each side. Site A and site B each have several local router hops.

We currently run Rip v2 at each site. Is it possible to forward Rip broadcasts through the VPN or is it time to look at adopting a more complex routing protocol, such as OSPF?

Any feedback is apprecaited. Thanks!

Re: site to site routing protocol best practice

Jeremy,

It is not possible to forward RIP broadcast through the VPN Tunnel between the ASA. Some of the options are:

1. Configure a GRE Tunnel between the routers and encrypt the Tunnel Source and Destination on the ASA.

2. Run OSPF on ASA and across the VPN Tunnel.

3. Redistribue RIP into OSPF

I think at this point of time, you are better of configuring a GRE Tunnel between the two routers and encrypting the GRE Tunnel on ASA.

Let me know if it helps.

Regards,

Arul
