Guys,

 

I have a question here :

 

When I have a topology R1-----R2------R3

                                                                |

                                                                |

                                                                R4

 

Somehow R1, and R3 is running eigrp protocol

 

R2 is runnign eigrp and ospf routing protocol

R4 is running OSPF

 

Route on R1 :

 

O 174.1.26.0/24 [110/2] via 174.1.23.2, 00:05:49, Multilink1 and
redistribute to eigrp

 

So I have scenario somehow R2 have external EIGRP from R1 but it was beaten
by OSPF AD, so OSPF won

 

the route become inaccessible :

O IA 174.1.26.0/24 [110/6] via 174.1.31.9, 00:58:19, FastEthernet0/0.13

 

P 174.1.26.0/24, 0 successors, FD is Inaccessible, serno 0

        via 174.1.13.3 (10537472/10025472), Serial0/1

 

so, I notice the route is not being advertise to R3, eveN R3 is using only
EIGRP protocol.

 

So I guess when the transit router not install the route, it not gonna
advertise to any their neghbor. Is that a correc behaviour ?
