rip v2 advertisements

[carl_townshend]

If I have a router advertiseing the network 172.16.38.0/24 running rip v1 and another router running rip v2 with the no auto summary command configured, and also advertising the same network , what will the difference be in the routing table ?

[stephtchoko]

rip version 1 is a classfull protocol, automaticaly summary at boundary and it doesn't advertise subnet mask in rounting exchange.

rip version 2 is classless protocol, automaticaly summarise at classful boundary, if your disable autosummary; it 'll advertise a subnet at classfull boundary.

Please hope this help and rate this post.

Would this to be neighbouring routers or only when it goes through a router on a different subnet ? Also does rip send updates to only its neighbours on the same subnet, whereas eigrp sends them to all known routers in its table ?

[stephtchoko]

rip v1 use broadcast to exchange routing information with its neighbors

rip v2 use muticast 224.0.0.9 to exchange routing information with its neighbor

with rip network command is to put a particular network on rip database. router Rip have :

- neighbor table

- routing table

Eigrp use multicast 224.0.0.10 to exchange routing information. Eigrp router have 3 tables:

-topology table

-neighbor table

-routing table

for 2 eigrp router can be neighbor if :

- AS is match

- metric is match

-send hello on interface to which neighboring 'll be negociated

Eigrp router send network learn by eigrp to its neighbor, not to all know router.
