Cisco IP Routing Protocols: Trouble Shooting Techniques (Charles River Media Networking/Security)

Redistribution leads to sharing of routing information among various routing protocols.

Redistribution requires detailed study of the network and careful planning, because the routing tables become more complex after incorporating redistribution.

The common problems due to redistribution are probable routing loops and nonoptimal path selection.

Routing loops arise due to inconsistencies in the routing states of different routers present in an interconnected network.

In the case of nonoptimal path selection, the data delivery time is longer, resulting in delay and less network performance.

To prevent problems related to redistribution, use route maps and distribution lists in order.

There are no generic Cisco IOS commands with which to troubleshoot all types of redistribution scenarios.
