Points to Remember

• 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.
