Rip V2, EIGRP
RIP version 2, EIGRP
EIGRP (Enhanced IGRP) has replaced IGRP. With the way EIGRP is set up as a protocol it is possible to implement a newer router that only supports EIGRP into a network that is running IGRP. Honestly network admins should be pushing for EIGRP if they are still on IGRP as for many features and advantages EIGRP has over IGRP. Directly from Cisco.com: "Enhanced IGRP provides compatibility and seamless interoperation with IGRP routers. An automatic-redistribution mechanism allows IGRP routes to be imported into Enhanced IGRP, and vice versa, so it is possible to add Enhanced IGRP gradually into an existing IGRP network." EIGRP:Enhanced Interior Gateway Routing Protocol IGRP: Interior Gateway Routing Protocol *IGRP and EIGRP are both Cisco proprietary routing protocols.
we would need to redistribute ospf routes into eigrp and vice versa. redistribution will have to be done on an ASBR(autonomus system boundry router) eg: we have an ospf process wid process id 10 running and eigrp with ASN 20 running in our network redistribution on ASBR would be conf t router ospf 10 redistribute eigrp 20 subnets metric 1 and in eigrp conf t router eigrp 20 redistribute ospf metric 1 1 1 1 1 we see i used 5 ones in eigrp process to redistribute opsf into eigrp. thes 1's are metrics for eigrp namely load bandwidth delay reliability

EIGRP is a Cisco proprietary routing protocol and therefore can only be used with Cisco routers.You can do route redistribution on Cisco routers, this allows you to take routes from another routing protocol (such as OSPF or RIP) and place them into the EIGRP network that way downstream nodes can be informed of routes available.
Compared to RIP, EIGRP has a lower administrative distance. Compared to EIGRP, RIP has a higher metric value for the route. Compared to RIP, the EIGRP route has fewer hops. Compared to RIP, EIGRP has a faster update timer.

Enhanced Interior Gateway Routing Protocol (EIGRP) was once as Cisco Propitiatory routing protocol for Cisco routers. However many routers that are not Cisco now support the use of EIGRP.
Which default EIGRP configuration must be modified to allow an EIGRP router to advertise subnets that are configured with VLSM
