Configuration Guidelines::
IGP Used "ISIS" Level 2 between PE1 & PE2. Loopbacks in Level 1 and
PE1 & PE2 in different area.
ATM Backbone in Provider Network
End User Connected with to CE1A Router using Microsoft Loopback Adapter through the Cloud.
IGP for CE Domain is EIGRP between CE1A and PE1 & RIP between CE2A and PE2
PPP Link used between PE-CE
TE Tunnel 100 between PE1 & P
