Implementing OSPF Domain-ID in MPLS L3 VPN LAB

Configuration Guidelines::

VRF Used "CEA"
RD Used "64513:1"
RT Used "64513:100"
AS Used "64513"
PE-CE Routing Used "OSPF"
IGP Used "ISIS" Level 2 between PE1 & PE2 .Loopbacks in Level 1 and PE1 & PE2 in different area.
OSPF Domain-id ::
Before”PE1 -172.16.10.1 & PE2 – 172.16.20.1”
After “PE1 -172.16.10.1 PE2- 172.16.10.1”

Implementing MPLS L3 VPN with Different PE-CE Routing Protocol OSPF & EIGRP

Configuration Guidelines::

VRF Used "CEA"
RD Used "64513:1"
RT Used "64513:1"
AS Used "64513"
PE-CE Routing Used "OSPF" for CE1A & PE1 & "EIGRP" for CE2A & PE2
IGP Used "ISIS" Level 2 between PE1 & PE2 .Loopbacks in Level 1 and PE1 & PE2 in different area.

Implementing MPLS L3 VPN with Different PE-CE Routing Protocol RIP & EIGRP LAB

Configuration Guidelines::

VRF Used "CEA"
RD Used "64513:1"
RT Used "64513:100"
AS Used "64513"
PE-CE Routing Used "RIP" for CE1A & PE1 & "EIGRP" for CE2A & PE2
IGP Used "ISIS" Level 2 between PE1 & PE2 .Loopbacks in Level 1 and PE1 & PE2 in different area.
