IP-RIP Delay Start

Some non-Cisco routers will not allow an MD5-authenticated RIPv2 neighbor session to start when the
sequence number of the first MD5 packet received from the Cisco router is greater than 0. The IP-RIP
Delay Start feature is used on Cisco routers to delay the initiation of RIPv2 neighbor sessions until the
network connectivity between the neighbor routers is fully operational, thereby ensuring that the
sequence number of the first MD5 packet that the router sends to the non-Cisco neighbor router is 0.
