Hi All,
I have a hub-and-spoke frame relay network, the DLCIs are as follows:
R2 (204)------------(402) R4
(205)------------(502) R5
R2 is the hub whereas R4 & R5 are the spokes.
R2 Config
---------
!
int s 0/0
ip add 10.10.10.2 255.255.255.0
encap frame-relay
no frame-relay inverse-arp
frame-relay map ip 10.10.10.4 204 broadcast
frame-relay map ip 10.10.10.5 205 broadcast
!
R4 Config
---------
!
int s 0/0
ip add 10.10.10.4 255.255.255.0
encap frame-relay
no frame-relay inverse-arp
frame-relay map ip 10.10.10.2 402 broadcast
frame-relay map ip 10.10.10.5 402 broadcast
!
R5 Config
---------
!
int s 0/0
ip add 10.10.10.5 255.255.255.0
encap frame-relay
no frame-relay inverse-arp
frame-relay map ip 10.10.10.2 502 broadcast
frame-relay map ip 10.10.10.4 502 broadcast
!
For the spoke routers, what's the difference if the frame map statement
pointing to each other has the "broadcast" keyword compared to without the
"broadcast" keyword? Either way, the spoke routers can ping to each other.
I believe it has no bearing on routing protocol neighbor adjacencies.
Adjacency is only established with the hub router as far as OSPF and EIGRP
are concerned.
My understanding is, the frame map statements are not even required between
spokes when we run EIGRP or OSPF (p2mp) on the frame relay network.
Please enlighten me.
Thank you.
B.Rgds,
Lim TS
