I've been running a tunnel with BGP to Hurricane Electric for a few years now on a Cisco 7600. I'm now in the process of migrating to a Cisco ASR9010 and I am having trouble even getting the tunnel to work.
!! previous Cisco 7600 tunnel config !!
interface Tunnel0
description DB7609: Hurricane Electric IPv6 Tunnel Broker
no ip address
ipv6 address 2001:470:xxxx:xx::2/64
ipv6 enable
tunnel source xxx.xxx.xxx.xxx
tunnel mode ipv6ip
tunnel destination 216.218.229.118
end
Through Cisco TAC, I got an IOS to IOS-XR config conversion which has been pretty useless as a great deal of it has not been valid.
Near as I can tell the only non-MPLS tunnel I can create requires GRE. Has anyone else encountered (and resolved) this?
!!
RP/0/RSP1/CPU0:DB-A9K(config)#int tunnel 0
% Ambiguous command: "int tunnel 0"
RP/0/RSP1/CPU0:DB-A9K(config)#int tunnel-

RP/0/RSP1/CPU0:DB-A9K(config-if)#tunnel mode ?
gre IP over GRE encapsulation
RP/0/RSP1/CPU0:DB-A9K(config-if)#tunnel mode
The following was my ASR9K config in it's entirety that doesn't work...
interface tunnel-ip0
description DB-A9K: Hurricane Electric IPv6 Tunnel Broker
ipv6 enable
ipv6 address 2001:470:xxxx:xx::2/64
tunnel source xxx.xxx.xxx.xxx
tunnel destination 216.218.229.118
which even without the "tunnel mode gre" specified, when I show interface it still shows "Tunnel mode GRE IPV4"
I an not familiar with this router, but other Cisco routers require the "enable unicast routing" command (or something really close to that)
Yeah, I'm beyond that (btw it's "ipv6 unicast-routing" on my 7600 ). The ASR9010 is already routing IPv6 via the tunnel created by the 7609S. I just want to get the tunnel off the 7600 and onto the ASR9K as the 7600 will eventually be removed. The ASR9000 series doesn't run Cisco IOS but runs IOS-XR (same as the CRS-1) which is similar to IOS in some ways but very different in others.
Well, I contacted Cisco TAC on this and got "We don't support this feature in XR." :(
