Is it possible to setup a frame relay lab using 3 routers where you can ping the interfaces on the router being used as the frame-relay switch? For example:
R1 is the frame-relay switch. Int S 1/0 is connected to int S 1/0 on R2. and R1 int S 1/1 is connected to int S 1/0 on R3. I can do a setup where R2 and R3 are the spokes with R1 being the hub. Both R2 and R3 can ping one another.
What I can't figure out is how to put an ip address on R1 interfaces where I can ping R2 and R3 from R1 and vice-versa.
After setting up frame-relay on R1 interfaces, I enter the following information for R1
int S 1/0
frame-relay route 100 int s 1/1 200
int S 1/1
frame-relay route 200 int s 1/0 100
R2 is setup as a multipoint interface:
int s 1/0.2 multipoint
ip address 126.96.36.199 255.255.255.0
frame-relay map ip 188.8.131.52 100 broadcast
R3 is setup as a point-to-point intreface
int s 1/0.3 point-to-point
ip address 184.108.40.206 255.255.255.0
frame-relay interface-dlci 200 broadcast
What I'm missing is how to setup the interfaces on R1 so I can ping them from the other routers. I appreciate any suggestions.
I figured it on my own. I connected R1 int s 1/3 to R3 int s 1/3 and configured frame relay on both interfaces along with ip addresses in the same subnet. R1 is the frame-relay switch. I was able to ping R1 from R3 and vice versa but I could not ping R1 from R2.
I tried different scenarios including adding frame-relay routes statements with the dlcis on R1 int s 1/0 (which was connnected to R2) and int s 1/1 (which was connected to R3) but nothing worked. I removed these last statements.
Since R2 int s 1/0.2 was a multipoint subinterface, I just had to add the new ip addresses for R1 and R3 to the dlci (same dlci for all 3 ip addresses)
int s 1/0.2 multipoint
frame-relay map ip 220.127.116.11 100 broadcast
frame-relay map ip 18.104.22.168 100 broadcast.
The first ip address is for R1 and the second ip address is for R3.
I have ip addresses on the following interfaces:
int s 1/0 no ip address
int s 1/1 no ip address
int s 1/3.1 22.214.171.124 255.255.255.0 (point-to-point - connected to R3 s 1/3)
int s 1/0.2 126.96.36.199 255.255.255.0 (multipoint - connected to R1 int s 1/0)
int s 1/0.3 188.8.131.52 255.255..255.0 (point-to-point connected to R1 int s 1/1)
int s 1/3 184.108.40.206 255.255.255.0 (point-to-point) connected to R1 int s 1/3)
FR over Hub-spoke; There are 3 common things to check for FR to work :
broadcast in frame-relay map statments;
Split Horizon on hub;
adding map statments on Spokes saying "to ping other spoke go thru hub"
there are some examples in my docs; if u still need help or have question, show us running config(s)
