6/30/2023 0 Comments Juniper route reflector![]() run ping 2.2.2.2 rapid count 5ĥ packets transmitted, 5 packets received, 0% packet loss So, we should be able to reach R1 to R3, which is needed to establish iBGP session from R1 to R3. Let’s verify our OSPF neighborship for all these three run show ospf neighborġ.1.1.2 ge-0/0/0.0 Full 1.1.1.2 128 run show ospf neighborĢ.2.2.2 ge-0/0/2.0 Full 2.2.2.2 128 run show ospf neighbor Set protocols ospf area 0.0.0.0 interface ge-0/0/2.0 Set protocols ospf area 0.0.0.0 interface ge-0/0/1.0 Set protocols ospf area 0.0.0.0 interface ge-0/0/0.0 We will add only router connected interfaces in this OSPF. Now, we will configure any IGP routing protocol, in this case OSPF. Set interfaces ge-0/0/1 unit 0 family inet address 172.16.0.1/24 Set interfaces ge-0/0/0 unit 0 family inet address 2.2.2.2/30 Set interfaces ge-0/0/2 unit 0 family inet address 2.2.2.1/30 Set interfaces ge-0/0/1 unit 0 family inet address 1.1.1.2/30 Set interfaces ge-0/0/1 unit 0 family inet address 10.1.1.1/24 Set interfaces ge-0/0/0 unit 0 family inet address 1.1.1.1/30 So, let’s get started.įirst of all, we will configure all the interfaces of these three routers. You also can bypass this problem, by configuring an IGP routing protocol like OSPF, which will help to reach all the routers. To solve it, we can use BGP Route Reflectors or BGP Confederations. However, full mesh is not always feasible and it’s nightmare for larger networks. Second, If we have a full mesh design, then this issue will not occur. You can learn more about iBGP rules from ciscopress. This is the rule of iBGP to avoid split horizon. ![]() That means, Router R2, will not be able to advertise learnt routes from R1 to R3 or R3 to R1. ![]() First, a router can’t advertise it’s learnt routes from a ibgp peer to another ibgp peer. ![]()
