If I am running Frame-Relay between two routers.
R1 is configured with point-to-point
and R2 is configured with phyiscal interface.
r1
-----
int s0.1 point-to-point
ip address 1.1.1.1 255.255.255.0
frame-relay intf-dlci 102
r2
-------
int s0
ip address 1.1.1.2 255.255.255.0
frame-relay map ip 1.1.1.1 201 broadcast.
Now I enable ISIS between those routers:
on r2 (with newer ios)
I could actually configure
isis network point-to-point
For example,
r2
------
int s0
ip address 1.1.1.2 255.255.255.0
frame-relay map ip 1.1.1.1 201 broadcast
isis network point-to-point
frame-relay map clns 201 broadcast---------> Do I still need this command,
that is my question
If lab doesn't allow to use isis network point-to-point command, then I will
have no choice, but to run tunneling
For tunneling, please verify my configs.
r1
-------
int s0.1 point-to-point
ip router isis
int tun0
ip unnumbered int s0.1
ip router isis
tunnel source 1.1.1.1
tunnel destination 1.1.1.2
r2
--------------
int s0
ip router isis
int tun0
ip unnumbered int s0
ip router isis
tunnel source 1.1.1.2
tunnel destination 1.1.1.1
tunnel destination 1.1.1.2
Some sources define not to run ip router isis on physical interface that is
used as an ip unnumbered under the tunnel interfaces. Instead just run ip
router isis on tunnel interfaces, and use passive interface command for
physical interfaces that is used as an ip unnumbered under isis rouing process
such as
r1
-------
router isis
passive interface s0.1
r2
------
router isis
passive interface s0
Any differences,
Ahmed
