Hi All,
during my studies about LDP as Signaling Protocol i found the below:
set routing-instances MPLS-VPLS-VLAN20 protocols vpls neighbor 192.168.10.32
set protocols ldp session 192.168.10.32 authentication-key "abcdef"
The first one should be
"Specify each of the PE routers participating in the VPLS domain. Configuring this statement enables LDP for signaling VPLS."
The second one is for:
"Configure LDP session parameters by specifying the session destination address."
As far as I understood the first one is needed for enabling LDP, so is a must to have command
The second command is only in case we want to use authentication between the LDP peers.
Could you please someone confirm?
More, analising the network, I have only 2 PE devices and MPLS/LDP is active between them.
Is there any way to distinguish, in the configuration, which signaling protocol is used to establish the transport tunnel(outer label)
and which signaling protcol is instead used for the inner label? (In this case the "service" which use the mpls is vpls).
As far as i understood so far, from my studies, the typical situation is
PE1 <-> P <-> PE1
In this case are needed 2 LDP session between
PE1 <->P
and
P <-> PE2
for creating the transport protocol
AND
and LDP session (targeted LDP session i guess) beetwen
PE1 <->PE2
for exchange the "inner" label.
In my case the topolgy is simple
PE1 <-> PE2 and is confusing me on how can i distinguish the 2 case above mentioned.
Thanks all!!
