[j-nsp] LDP breaks at MPLS/VPN Backbone

[Jack.W.Parks at alltel.com]

In simple terms, LDP will converge as fast as your IGP can converge.
Look into Bidirectional Forwarding Detection Protocol (on Juniper) to
speed convergence time.  As far as Fast Reroute, you need to understand
the topology requirements of fast reroute and deploy RSVP for signaling.

Subject: [j-nsp] LDP breaks at MPLS/VPN Backbone


Hi there,

My name is Maher and currently testing MPLS/VPN running on Cisco
devices. I would like to ask if there is a break in LDP at core
router(P), which sometimes due to misconfiguration or perhaps hardware
failures,in terms routing mechanism and update how does on each PE
routers detect the break in terms of running MPLS/VPN on Juniper devices
such as on M20?

For a normal IP packet, I presummed the traffic will flow but if vpnv4
routes?Normally, in Cisco devices, I need to implement MPLS FRR or TE.
How about in Juniper devices? Is there any method to re-route without
having a major migration on IP infrastructure?

thank you very much,

regards,

maher
