Hi,
I have a problem when creating xconnect from CRS router to 7606, the xconnect status always unresolved. The CRS and 7606 is directly
connected and here is the configuration :
CRS Configuration

Group TESTXCONNECT, XC VLAN123_TESTXCONNECT, state is unresolved; Interworking Ethernet
Not provisioned reason(s):
AC I/F not ready
AC: GigabitEthernet0/0/2/7.123, state is unresolved
PW: neighbor 1.1.1.105, PW ID 123, state is unresolved
any idea why the xconnect status is showing unresolved?
