Configuring Border Control Model

Border control model lets you specify the optical core tunnels to be advertised to edge packet topologies.
Using this model, the entire topology is stored in a separate packet instance, allowing packet networks where
these optical tunnels are advertised to use LSP hierarchy to signal an MPLS tunnel over the optical tunnel.
Consider the following information when configuring protection and restoration:
• GMPLS optical TE tunnel must be numbered and have a valid IPv4 address.
• Router ID, which is used for the IGP area and interface ID, must be consistent in all areas.
• OSPF interface ID may be a numeric or alphanumeric.
Border control model functionality is provided for multiple IGP instances in one area or in multiple IGP
Note
areas.
To configure border control model functionality, you will perform a series of tasks that have been previously
described in this GMPLS configuration section. The tasks, which must be completed in the order presented,
are as follows:
1 Configure two optical tunnels on different interfaces.
When configuring IGP, you must keep the optical and packet topology information in separate routing
Note
tables.
2 Configure OSPF adjacency on each tunnel.
3 Configure bandwidth on each tunnel.
4 Configure packet tunnels.
