Chapter 3 Information About Topology
Two Platforms on Parallel Links in Bump-in-the-Wire Topology
When using routing/switching protocols that perform load balancing as well, the load balancing
Note
capabilities should be disabled.
The transition to the backup SCE 1000 platform is transparent. Once the routers/switches detected that
traffic has been cut, they start sending traffic through the redundant link. After this occurs, the failed
SCE 1000 can be fixed/replaced with no downtime, since the box is effectively disconnected from the
network. After fixing/replacing the failed SCE 1000, you must copy the configuration of the current
active SCE 1000 to the fixed/replaced SCE 1000.
The backup and restore procedures used for copying policies and Service Configurations from one SCE
1000 to the next are detailed in the Cisco Service Control Application for Broadband User Guide.
