Here Router 1 is the hub and routers 2,3,4 are spokes..
CONFIGURATION:
ROUTER 1:
interface Serial2/0
ip address 10.0.0.1 255.255.255.0
encapsulation frame-relay
frame-relay map ip 10.0.0.2 100
frame-relay map ip 10.0.0.5 200
frame-relay map ip 10.0.0.4 300
ROUTER 2:
interface Serial2/0
ip address 10.0.0.2 255.255.255.0
encapsulation frame-relay
frame-relay map ip 10.0.0.1 100
ROUTER 3:
interface Serial2/0
ip address 10.0.0.5 255.255.255.0
encapsulation frame-relay
frame-relay map ip 10.0.0.1 200
ROUTER 4:
interface Serial2/0
ip address 10.0.0.4 255.255.255.0
encapsulation frame-relay
frame-relay map ip 10.0.0.1 300
FRAME-RELAY SWITCH:
interface configuration
interface--DLCI------NAME
serial0----100-------1-2
serial0----200-------1-3
serial0----300-------1-4
serial1----100-------2-1
serial2----200-------3-1
seiral3----300-------4-1
Frame relay
From port------------Sublink
serial0---------------1-2
serial0---------------1-3
serial0---------------1-4
By configuring so,we can reach only from Hub to spokes , to get a reach-ability between spoke to spoke we need to add static mapping as follows
ROUTER 2:
frame-relay map ip 10.0.0.5 100
ROUTER 3:
frame-relay map ip 10.0.0.2 200
Add the above commands under R2 and R3 then R2 can reach R3 which is spoke to spoke communication
Hi Kumar. Can you please explain to me how I can setup a hub and spoke topology like above with an OSPF routing protocol. I am having difficulties achieving this, thanks.
ReplyDeleteHi,
ReplyDeletethank you for ur comment. i explained the ospf over framerelay in the following post.please check
