Implementing EIGRP SoO Feature to Improving Routing Convergence in MPLS L3 VPN with Backdoor EIGRP Links LAB

COnfig Guide Lines
***************************************************************************************
ISP AS 64513
IGP is ISP used ISIS with Loopbacks in Level-1 and Backbone Links in Level-2
To avoid MP-iBGP Full Mesh PE2 forms CLuster ID 10.0.2.1 with PE1 and PE2 is the
Route-Reflector for this Cluster
PE2 has normal MP-iBGP Peering with PE3
VRF Used CEA
rd 64513:1
rt 64513:100
IGP is Cusomer Domain used EIGRP
PE-CE Routing Protocol EIGRP
Backdoor Links have bnadwidth set to Lower than MPLS Links for Low Preference
Site-Map used SoO with extcommunities:
'
64513:1000 for CE1A & PE1
64513:2000 for CE2A & PE2
64513:3000 for CE3A & PE3
