â– Identifier (1, 2, or 3) of the ATM Martini cell packing timer that you want to
use to detect timeout of the cell collection threshold

5. Create an MPLS relay connection to the loopback interface on the egress router.
The VC ID (1 in this example) must be the same on both sides of the connection.
host1(config-subif)#mpls-relay 6.1.1.1 1
host1(config-subif)#exit
6. Repeat Steps 1 through 5 on the egress router, creating an MPLS relay connection
to the loopback interface on the ingress router.
The values you configure for the ATM Martini cell packing timers and cell
concatenation parameters need not be the same on the ingress and egress
routers, although matching values are permitted. The virtual connection ID (VC
ID) value in the mpls-relay command, however, must be the same on the ingress
and egress routers.
