eigrp withdrawing method

[Arun]

There is no flags in eigrp update messages to withdraw the routes.How the neighbors are communicated about invalid routes?

Hi,

EIGRP will update the same prefix with infinity metric. Any router on receiving a prefix with infinity metric will consider it as withdraw and remove from local table.
