Where to Go Next
Where to Go Next
After the RPM-PR card is initialized and any required redundancy is established, you can configure the
RPM-PR card to operate in either of the following roles:
• Label Switch Controller (LSC)
• Label Edge Router (LER)
In either the LSC or the LER role, the RPM-PR communicates with other ATM switches using MPLS
AXSM communications links. For instructions on configuring AXSM trunks and lines to support MPLS,
see to Chapter 6, “Provisioning AXSM Communication Links.”
When operating in the LER role, the RPM-PR card can use Ethernet connections on the RPM-PR back
cards to connect to IP networks. The LSC and LER roles, and the RPM-PR Ethernet connections, are all
defined using Cisco IOS commands, which run on the RPM-PR card. To start using Cisco IOS CLI from
a switch CLI session, use the cc command to change cards to the RPM-PR slot. For instructions on
configuring the RPM-PR card with Cisco IOS commands, refer to the Cisco MGX Route Processor
Module Installation and Configuration Guide, Release 2.1.
