routing protocols

[carl_townshend]

When using these we advertise the network according to what ip the interfaces are on, does this just include the interface in the routing protocol to be part of the process ?

hi,

The routing protocols usually map the networks to an interface in its routing table by using which the network can be reachable

Thanks,

Well, honestly depending on the routing protocol you are going to use. EIGRP and OSPF for example depend on which interface will form neighor relation ship and depending on what network is on the interface it will be advertised. However, BGP does not depend on the interface and you use the network command to advertise the subnet you want.

Therefore, when you issue the network command under the EIGRP and OSPF it means you are saying that these interfaces can send and receive hello packets and form adjacency or neighbor relation ships. However, the advertised subnet will be that of the interface. For example, if you issue the command network 10.20.30.1 0.0.0.0 this means only this interface will form neighbor relationship however the advertised subnet would be 10.20.30.0/24 in case this is the interface subnet.

Please rate if you find this helpful,

Thanks,
