RR Configuration:
router bgp 100
neighbor IBGP peer-group
neighbor IBGP route-reflector-client
neighbor 10.1.1.1 remote-as 100
neighbor 10.1.2.2 remote-as 100
neighbor 10.1.3.3 remote-as 100
The network administrator configured the network to establish connectivity between all devices and notices that the ASBRs do not have routes for each other.
Which set of configurations resolves this issue?
The correct configuration to resolve the issue is to assign the neighbors to the specified peer-group (IBGP) on the route reflector (RR). This ensures that the route advertisements are properly reflected by the RR to the other iBGP routers. The configuration specified in option D achieves this by assigning each neighbor to the IBGP peer-group. This way, the RR will correctly reflect routes between the ASBRs, thereby establishing connectivity between them.
RR is set as the route reflector for the peer-group called IBGP. For this to take effect, we need to add the neighbors to the perer-group, which is solution "D". After this, route advertisments will be reflected by RR to the other IBGP routers. https://community.cisco.com/t5/switching/peer-group-on-a-route-reflector/td-p/1536406 https://networklessons.com/bgp/bgp-route-reflector https://www.oreilly.com/library/view/cisco-ios-in/0596008694/re638.html
