EIGRP/stub and Query

Hello

There is LAN segment with R1,R2,R3 running EIGRP. R3 is configured as stub. R1 and R2 are connected to other LAN segment. R1's connection to that segment is goin down. R1 send update that it has no longer that prefix. R3 receives it and let's assume that it has not feasible successor for that route. Will R3 query both R1 and R2 ? Does stub functionality changes this behavior or not ?

Thanx

Hi

If stub feature is enabled on R3, R1 and R2 will not send the QUERY to R1.

Re: EIGRP/stub and Query

Hi ,

If you look at how eigrp negihbour relationship forms there is a stub field.

When the router become the neighbor the router configured with stub command set that field and send it to the neighbour,so the neighbour knows in advance the the connected neighbour is stub and do not send query message to it.
