Hii James, i have a trouble with my mpls hierarchy
configuration setup.
My hierarchy is:
*---------LSRB---------*
| |
| |
HostA---------LER1--------------------LER2-----------HostB
| |
| |
*---------LSRB---------*
Network address:
-->HostA to LER1 : 10.14.1.0/24
-->LER1 to LSRB : 10.14.2.0/24
-->LER1 to LSRB : 10.14.4.0/24
-->LER1 to LER2 : 10.14.3.0/24
-->LER2 to HostB : 10.14.7.0/24
I used :
-->mpls-linux-2.6.9.tar.bz2
-->iproute-2.6.9-3mpls1_946.i386.rpm
-->kernel linux-2.6.9.tar.bz2
I confused when i used static route mpls from LER1,i
couldn't route with 3 gateway, there are from
LER1 with LSRA as first gateway
LER1 with LER2 as second gateway
LER1 with LSRB as third gateway.
I have used static but when setting up the seond gateway
failed with RNETLINK.You can see below
LER1
------
mpls nhlfe add key 0 instructions push gen 100 nexthop
eth1 ipv4 10.14.2.2
(key1)
ip route add 10.14.5.0/24 via 10.14.2.2 spec_nh 0x8847
key1 (first gateway)
mpls nhlfe add key 0 instructions push gen 200 nexthop
eth1 ipv4 10.14.3.2
(key2)
ip route add 10.14.5.0/24 via 10.14.3.2 spec_nh 0x8847
key2 (second gateway)
RTNETLINK:no success
---------------------------------------------------------------------------
Do I have to use dinamic route with Quagga???
Ihave compiled quagga-0.97.3-1.FC3mpls1_946a.i386
successfully,but i ccouldn't enter to CLI router.Do I need
other packages??
Could mpls command use priority route if the first gateway
faild automaticaly routing move to second gateway or to
third gateway????
Please give me some suggestion.

Hello:
I try to test a example as follows. I want to establish two way =
LSP(from LER1 to LER2 using label 1000, and LER2 to LER1 using label =
1002). When I finish the configuration and using "ping" (from LER1 to =
LER2) to test. I can't see the "ping reply". I guess the LSR's =
configuration has problem. Please tell me my configuration of LSR is =
correct or not? Furthermore tell me how to modify the =
configuration...thanks=20
ps. Thanks for your attention and sorry about my poor English.

LSR is the problem. Instead of adding routes you need to add cross connect= s. mpls xc add ilm_label gen 1000 ilm_labelspace 0 nhlfe_key 0x2 mpls xc add ilm_label gen 1002 ilm_labelspace 0 nhlfe_key 0x3 On Mon, Dec 19, 2005 at 03:03:13PM +0800, Allen wrote: > Hello: > I try to test a example as follows.
