How to prevent Routing updates on interfaces of Cisco Routers
When we configure a routing protocol on Cisco IOS Routers, it is important to consider preventing Routing updates sent on interfaces that are not required to (say a LAN where there is no other router in the segment to receive any updates). This ensure we are not passing updates that could cause network issues. Needless to say, the network becomes less chatty and can make life more easy when sniffing or spanning for network troubleshooting. In Cisco IOS we can globally or selectively prevent interfaces on which we do not want routing updates to be sent. Ideally, it would be better that we do thisRead More →
