Quite elementary but thought I run it by the group
I have come across sevreal FR hub and spoke questions but this one has put me in a state of doubt.
Question states do no use sub-interfaces for FR links but use only on Hub and spoke. Note the key word here is "and".
I usually come across situation where the Hub is the only place for a sub-interface in the entire FR topology.
As per the question above, it seems I should have a sub-interface on each Fr interface belonging to Hub and spoke environment .i.e including the spokes as well.
let's say A is the hub and B and C are spokes and here are their configs ..
Router A (Hub)
int s0
encap frame-relay
no frame-relay inverse-arp
int s0.29 multipoint
ip address 10.10.10.25 255.255.255.0
frame relay map ip 10.10.10.26 dlc# broadcast
frame relay map ip 10.10.10.27 dlc# broadcast
Router B (Spoke)
int s0
encap frame-relay
no frame-relay inverse-arp
int s0.29 multipoint
ip address 10.10.10.26 255.255.255.0
frame relay map ip 10.10.10.25 dlc# broadcast
frame relay map ip 10.10.10.27 dlc# broadcast
Router C (Spoke)
int s0
encap frame-relay
no frame-relay inverse-arp
int s0.29 multipoint
ip address 10.10.10.27 255.255.255.0
frame relay map ip 10.10.10.25 dlc# broadcast
frame relay map ip 10.10.10.26 dlc# broadcast
Does my solution make sense with regards to the stated question ?
Or Should there only be one sub-interface i.e. on the hub.
