Thread: [mpls-linux-general] mpls FC3 hierarchy question

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi James,sorry i want to ask some ques
I had installed FD3 in my computers and have compiled 
mpls-linux successfully.

I have used : 1.linux-2.6.9.tar
	            2.mpls-linux-1.946a.tar
	            3.iproute-2.6.9-3mpls1_946.i386.rpm
	            4.quagga-0.97.3-1.FC3mpls1_946a.i386.rpm

I have the following simple topology

ip(11.0.4.1) --- LER1 (11.0.1.1) --- (11.0.1.2) LSR1 
(11.0.2.1)
--- (11.0.2.2) LSR2 (11.0.3.1) --- (11.0.3.2) LER2 --- 
ip(11.0.5.1)

or in MPLS network label topology:
                 101
       100       201       200
LER1------LSR1------LSR2------LER2

Between LER1 and LSR1 use label 100
Between LER2 and LSR2 use label 200
Between LER1 and LER2 use label 101 and 201
assumtion we send with eth0 and receive with eth1
I want ip(11.0.4.1) with/to ip(11.0.5.1) can communicate

I have used the example hierarchy in 
http://mpls-linux.sf.net command,but i have confused 
because in the http://mpls-linux.sf.net only use two 
computers.

I have configured with the following command:

Setup LSP between Ingress LER1 and LSR1:
[root@LER1]#mpls nhlfe add key 0
(key 2)
[root@LER1]#mpls nhlfe change key 0x2 instructions push 
gen 100 nexthop eth0 11.0.1.2
[root@LER1]#ip route add 11.0.5.1

[root@LSR1]#mpls labelspace add dev eth1 labelspace 0
[root@LSR1]#mpls ilm add label gen 100 labelspace 0

Setup LSP between Engress LSR2 and LER2:
[root@LSR2]#mpls nhlfe add key 0
(key 2)
[root@LSR2]#mpls nhlfe change key 0x2 instructions push 
gen 200 nexthop eth0 11.0.3.2

[root@LER2]#mpls labelspace add dev eth1 labelspace 0
[root@LER2]#mpls ilm add label gen 200 labelspace 0

Setup LSP between LSR1 and LSR2 (label 101):
[root@LSR1]#mpls nhlfe add key 0
(key 2)
[root@LSR1]#mpls nhlfe change key 0x2 instructions push 
gen 101 nexthop eth0 11.0.2.2

[root@LSR2]#mpls labelspace add dev eth1 labelspace 0
[root@LSR2]#mpls ilm add label gen 101 labelspace 0

Setup another LSP between LSR1 and LSR2 (201 label):
[root@LSR1]#mpls nhlfe key 0
(key 3)
[root@LSR1]#mpls nhlfe change key 0x3 instructions push 
gen 101 nexthop eth0 11.0.2.2

[root@LSR2]#mpls ilm add label gen 201 labelspace 0

Forwarding traffic for the 201 LSP to ride on the 101 LSP:
[root@LSR1]#mpls nhlfe change key 0x3 instrutions push gen 
201 forward 0x2

[root@LSR2]#mpls ilm add label gen 101 labelspace 0

Some question that i want to ask:
1.Please check, is my command true and how the solution?
2.How to tie the LSPs together
3.How to configure via tunnel interface
4.How to use quagga,i cannot get the command (config t)

sorry i have much ques,THANKS VERY MUCH BEFORE with your 
attention
