Hi Did anyone test this scenario before. Assuming eth1 eth2 and eth3 are in the same area and the same subnet (Let's say 192.168.2.0/24). From the RFC, both eth1 and eth2 are considered togather to DR election cause they have same router ID. Then as...
Hi I try to set up a very simple OSPF configuration. Cause I do not have Cisco router, it is tested by qugga in VM.RTA(192.168.0.1) <------->(192.168.0.2) RTB (192.168.2.2)<--------> (192.168.2.3)RTCAll of interfaces belong back-bone area. When I pi...
Hi It is a quite simple question. If there are multiple available paths from A to B (same area). Router will only update the shortest path(least cost) in the routing table or more than that?Thanks in advance.
Any reason? RFC says it is not allowed or some design consideration?Have you tested this case in your environment. Actually, as I know, some routers can work in this caseIt is appreciate if you can explain more detailed. Thanks
I do not have the environment, all of test is running in VM with quagga. I am not sure if any Layer 2 protocol block the OSPF multicast.Could you explain what should happen and what exact status interfaces should be.For example, if eth1 is DR, eth3 w...
Hi EugenThanks for your suggestion, it does not work. And I personally dun think there is any difference between 0.0.0.0 and 0And I am not sure whta is process ID, is it router ID? If yes, quagga will assiagn the router ID automatically.ThanksChen X...
Hi Dan I think the routing table in RTB is wrong. I also capture the ping packet, when I ping 192.168.2.3 from RTA, the ping request packet only can be catched in ETH1 RTB. But why? Did I miss anything for OSPF configration.RTA:~# route -nKernel IP r...
I believe the neighborship has been established. Cause I can ping 192.168.0.2 from RTCAnyway I paste more information below as you requested. Thanks in advanceRTAospfd# show ip ospf interface eth0 is up ifindex 2, MTU 1500 bytes, BW 0 Kbit Intern...
