Thanks for answer James,
I'm trying to setup ospf but I still have some problem configuring it...
Anyway, I have some more detail for my previous issue :
Using "traditional" IP (no label), I can still reach direct neighbours but not gatewayed one. That can explain that RIP tables are correctly updated.
As I said in my previous mail, when I ping a distant network, not trafic goes out the originating host. Moreover dmesg on this host shows lines like for each emission attempts :
mpls_bogus_output: 10.12.3.11 -> 10.12.4.13, ?
Moreover ip route (correctly patched...) displays :
10.12.4.0/24 via 10.12.3.13 dev eth1 lsp 0x2 proto zebra equalize
10.12.3.0/24 dev eth1 proto kernel scope link src 10.12.3.11
10.12.2.0/24 via 10.12.3.13 dev eth1 lsp 0x2 proto zebra equalize
10.12.1.0/24 dev eth2 proto kernel scope link src 10.12.1.11
127.0.0.0/8 dev lo scope link
What the "lsp 0x2" means for the rip learned routes ? I did not configure any mpls on the distant router !
What means the mpls_bogus_output message ? I only want to emit regular ip ping.
Beside this, if I turn off dynamic routing and configure static routes, everything works perfectly... Do I need to use a patched version of zebra ? Did I miss a configuration step ? Can't I use regular ip ping in the same time than mpls ?
Thx :)
Eric
