Hi All
I am having issues with running IS-IS between my ASR9006 and Cat6500 switch.
I am running IOS XR 4.0.3 with Mini and MPLS packages enabled.
My configuration on ASR is below, please can someone confrim my configuration on the ASR9000 is correct and why its not working?

Hello,
Can you describe your issues in more detail? So far you have only indicated that something is not correct but it is not clear which problems exactly are you dealing with.
What is the output of the following commands:
Also, are you perhaps using the wide metrics on your Cat6500? Your ASR is not currently configured for wide metrics, and this incompatibility usually results in no prefixes being populated into the routing table.
Best regards,
Peter

Hello,
Try removing the entire address-family ipv6 unicast section from your configuration, as you currently do not appear to need the IPv6. It seems that the router tries to run IPv6 IS-IS on your interfaces and they do not have IPv6 enabled (note the "IPv6 Unicast not cfg on intf" complaint on each interface).
Best regards,
Peter

if you enabled "address-family ipv6 unicast" or "address-family ipv4 unicast" in ISIS, IPv4 or IPv6 must be turned on inteface level, otherwise you will get the message like this"
Interfaces supported by IS-IS:
Loopback0 is running passively (passive in configuration)
GigabitEthernet0/5/1/0 is running passively (active in configuration)
