We already have configured the interface with administrative group 4 So Why we couldn’t add another administrative group by value 2.
mpls te link administrative group 4
We can change administrative group value to include the two values 2 (0000 0010) and 4 (0000 0100) to be 6 (0000 0110) so that link contain the two colors and by changing affinity property and mask values under MPLS TE Tunnel when we are trying to match the administrative group values for interfaces we can check the three values 2, 4, 6 separated.
mpls te link administrative group 6
Tunnel interface configuration example:
ip address unnumbered interface LoopBack0
tunnel-protocol mpls te
mpls te affinity property 2 mask 2 (OR mpls te affinity property 4 mask 4, mpls te affinity property 6 mask 6)
And this link will match all these values.
