I have a 871-SEC-K9 in my IPv6 lab running 2 tunnels to 2 different brokers. The tunnels are up and working fine. I can ping anything from whatever source (tunnel0 and tunnel1). I have a vlan interface that has both global ipv6 address from the allocated subnet given by my 2 brokers. The hosts (a FreeBSD machine and a Win7 machine) are receiving both router advertisements as they have auto-configured based on both global ipv6 address from the vlan interface. Both hosts are able to ping both addresses.
Now here's my problem, I'm using:
ipv6 route ::/0 Tunnel0
and if my Tunnel1 goes down, my hosts no longer have access to IPv6-enabled internet. Now adding a second ::/0 route to that tunnel didn't help my problem (and actually caused other problems as expected).
What is the correct method for what I'm trying to do? I've looked at Cisco's IPv6 docs (especially about multihoming) but nothing has helped so far.
Re: Connection redundancy with dual ipv6ip tunnels
Ok, so no one has any answers so far... but I kept looking. I'm almost there. And I'm at 3 tunnels for the heck of it. Here's what I have now:
ip address 192.168.1.1 255.255.255.0
ip nat inside
ipv6 address 2001:470:xxxx:1::1/64
ipv6 address 2001:5C0:xxxx:B900::1/64
ipv6 address 2001:4978:xxxx:1::1/64
ipv6 policy route-map he-next-hop
ipv6 route ::/0 Tunnel2
ipv6 route ::/0 Tunnel1
ipv6 route ::/0 Tunnel0
route-map sixxs-next-hop permit 10
match ipv6 address sixxs-pool
set default interface Tunnel2
route-map go6-next-hop permit 10
match ipv6 address go6-pool
set default interface Tunnel1
route-map he-next-hop permit 10
match ipv6 address he-pool
set default interface Tunnel0
ipv6 access-list he-pool
permit ipv6 2001:470:xxxx:1::/64 any
ipv6 access-list sixxs-pool
permit ipv6 2001:4978:xxxx:1::/64 any
ipv6 access-list go6-pool
permit ipv6 2001:5C0:xxxx:B900::/64 any
and with an ipv6 traffic-filter in each tunnels.
This is almost working like I want it to, except I am unable to put all three route-map in my vlan interface. That way I could forward traffic based on the source IP to the correct tunnel. How do I get all three route-map working at the same time?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
