Hi,during preparing snmp on cisco switches I am confusing if I need to set the snmp-server host under passive/answer mode (switch can answer the query by snmp server. No need to send trap proactively) ?Thanks

Hello, I am running a basic EIGRP configuration in GNS3 and noticing R9 can not onboard the network 10.1.1.1/32 and 10.2.2.2/32 advertised by R8 when interface g0/3 is active. Even I am using the command show ip eigrp topology all-links I can only g...

hello,can someone elaborate why EIGRP needs a RID? Does it just help to avoid a loop? Thanks

Hello, I am learning the EIGRP basics in GNS3 and have added loopback interfaces and interfaces gi0/0 into the EIGRP AS. During establishing adjacency, I notice that the EIGRP update packet sent by R2 has a next-hop ip 0.0.0.0. Can someone explain w...

When I run the cli show spanning-tree vlan 1, I notice the port type is shr. What does shr stand for? Switch#show spanning-tree vlan 1 VLAN0001 Spanning tree enabled protocol rstp Root ID Priority 32769 Address 0c21.0d37...

Yes, the load balancing might be the root cause. The load balancing on R8 means that R7 and R9 are R8's successor. Thus, R9 won't accept/will delete the advertisement 10.1.1.1/32 from R8 because R9 is the successor of R8. If I adjust the metric on R8...

I have uploaded the config files and event file. I cleared the adjacency between R8 and R9. During establishing adjacency I ran show ip eigrp events on R9. In the eigrp event I can see R9 received the 10.1.1.1/32 from R8 but then deleted it. ...

Hi Mentor, can you check if R4 has an eigrp route to 1.1.1.1/32 with the next-hop to R3? In my case, R4 didn't has this route even when I use the command show ip eigrp topology all-links. If R3 advertise it to R4, R4 would keep it in the EIGRP databa...

Hi David,Thanks for the inspiring answer.The R8 is load balancing and won't advertise the routes from R7 to R9 since the routes from R7 are not BETTER than the routes from R9. BTW, do you have a document where I can learn this EIGRP character? Or is ...

Hi Mentor,EIGRP is using split horizon to avoid a routing loop. Is RID the check point of split horizon?
