There is a TAC article that talks about using GRE tunnels to pass
routing information.

Subject: OT: Passing Routing information across Firewall
Hi All,
This may be a bit OT.
does anybody know how to pass routing formation across the firewall ?
tunnel would be an option to pass routing updates ONLY. The "normal" IP
traffic should still passes through the firewall. Assuming the firewall
does not support any routing protocol. Here is a little diagram hope it
might clarify the question.
10.1.1.0/24--R1--192.168.1.0/24--Firewall--192.168.2.0/24--R2--10.2.2.0/
24
R2 needs to learn 10.1.1.0/24 from R1
R1 needs to learn 10.2.2.0/24 from R2
tunnel between R1 & R2 is an option. but only to pass route
update/hello only. all IP traffic must route through the firewall.
Any help would be appreciated
Thanks in advance
Charles
