I am looking for some pointers for an issue I am stuck with on Broadband PPPoE across MPLS Backbone.
I am implementing PPPoE from User LAN GW to the Broadband RAS using an MPLS L2 VPN as transport
across the MPLS Backbone. The setup works all good with the MPLS Psuedowire with Normal TE Tunnels
running in the Core.
The Problem is the moment I switch to EXP aware TE Tunnels to achieve CBTS(Class Based Tunnel Selection)
to implement MPLS AToM Vll(Virtual Leased Line),my PPPoE session goes down at the Broadband RAS.
I have not tried to do any debug or anything till now,but I definitely see the session for the User being not active and
the IP being returned to the local pool.
Any pointers to understand this typical behaviuor over EXP aware TE Tunnel for the PPPoE Session. The PPPoE
session works all fine for the normal non-exp aware TE Tunnels.
Setup is like this
NAT MPLS Traffic Engineering Tunnel
CE_LAN---(OSPF)--LAN_GW--(PPPoE Dialer Interface1)---edge1.pop1--core1.pop1-edge1.noc------BRAS--(EBGP)--Internet GW
MPLS L2 MPLS L2
