Enable eigrp stub routing to stabilize the network, reduce bandwidth and cpu use, and speed convergence by limiting queries to stub areas, which only know what they advertise.
In stuck in active, a router sends a query after losing a neighbor and may reset it if no reply arrives, ending the session; two packets extend wait on links.
Discover how OSPF virtual links connect noncontiguous areas to the backbone, making area zero effectively contiguous. Use them sparingly and as temporary fixes until full contiguity is achieved.
Explore how to assign default metrics when redistributing routes between RIP, OSPF, EIGRP, and BGP, and understand external route types and their impact on routing tables.
Explore how redistribution between routing protocols can create route feedback and possible routing loops, and examine split-horizon concepts and strategies to manage multiple entries and exits.
Learn how route reflectors propagate updates across networks, showing why root reflectors scale beyond three or four routers for efficient, easy-to-configure BGP design in large IGP environments.
Verify that loopback addresses are advertised and reachable to establish iBGP sessions. Ping the loopback on the peer and ensure a route exists to the loopback.
Explore how to operate on RD in MPLS VPN by using MPLS BGP to advertise 96 bit VPN v4 addresses across the network.
Tear down dynamic tunnels after a period of inactivity using a timeout of 600 seconds to retire unused dmvpn connections.
Debug dhcp v4 and v6 traffic, locate misconfigurations in pools, relay addresses, and default routers, then fix and verify with ping.
