interface-group (Decapsulate GRE)


Hierarchy Level


Allows you to explicitly specify and add an interface group to packets after they have undergone GRE decapsulation. In releases prior to Junos OS Release 14.1, the interface group upon decapsulation was always 0 and could not be changed.

In Junos OS Release 14.1 and later, you can assign any arbitrary value in the range of 1 to 255 to the packets’ interface-group upon GRE decapsulation. For example, you could use this command to retain the original interface from which the packet was received (if no value is set, the default interface group is 0). You could also use it to ensure that all decapsulated GRE packets are placed in the same group, for example to trigger additional filtering in the forwarding table on the basis of the this data from the inner packet.

The value used in interface-group is set after the GRE packet is decapsulate by a filter action in a filter attached to a given ingress interface.
