There's a lot more to RID's and LSA operation than above but in a shell of a nut. The OSPF router does the same.Ī router seeing it's own RID will reject the LSA thinking that there is a loop in the network, so the RID is used to get a picture of the network and to prevent loops occuring in the topology. it makes it easier to piece the jigsaw puzzle together again. i can able communicate with each other no issues: Problem is i configured line vty on all routers and able to telnet using routers. Now, i have configured loopback interfaces on all three routers and have configured static routing between them to communicate. The LSA's will contain the RID are then processed by other routers to get a picture of the network, this operation is like taking a jigsaw puzzle numbering all the pieces with each piece also having information about which other RID ID that particular interface peers with. i have a topology with three routers interconnecting eachother. 3) add a route on your core switches for the loopback pointing to the vlan 10 SVI ip address. 2) give the SVI for vlan a ip address and make it reachable from your core switches. 1) on the access switch configure a management vlan eg. ping 10.0.0.1 source x ping 10.0.0. If it is acting as a L2 switch then you would have to do the following. Check IP connectivity between the two routers using the ping command. Configure the routers with the following parameters : - Clock : 250000. The point of the RID needing to be unique in OSPF is so that when the Router creates and floods Link State Updates (LSU) which contain the Link State Advwertisments (LSA) they will all have the originating routers RID. How can I ping with source option in Cisco Router I have a ISR 4321 Router, I want to ping from a source IP address: Routerping WORD Ping destination address or hostname ip IP echo ipv6 IPv6 echo there I have two question, how can I add source options in Cisco Router I tried use the. You can connect to the routers using CLI.Click to expand.Indeed it does, each OSPF process you enable on a router will select it's own unique Router ID (RID).
