Configuration Guidelines
*************************************************************
Scenario - An ISP having a big geographic presence wants to implement
Traffic Forwarding for his MPLS L3 VPN Customers across his Core across
differentTraffic ENgineering Tunnels.ISP has a ISIS Level-2 Core Backbone
with Edges in different POPs in ISIS Level-1 Domain.ISP has Mixed network of
ATM Point-to-Multipoint,ATM Point-to-Point Topology and Legacy Frame-Relay.
Design Considerations and Soultions:
Since ISP has Mixed Core of Legcay ATM/FR and we have to use Hirearchical
Focus is required on the ATM P2M Topology. Also ISP will use Multilink Frame Relay
to capitilize on the BW available in the core without provisioning More DLCIs between
two routers.
For Frame-Realy MFR we will need to configure MFR Interfaces and Assign IP and DLCI and
do CLNS Mapping for the DLCI with broadcast capabilites as the MFR will be by default
a P2M NBMA.
For P2M ATM ISIS will need to be confiured along with a CLNS Mapping for the ATM PVC having
broadcast capabilities as well as ATM PVC to IP Address Mapping for L2-L3 Resoultion.
Frame-Mode MPLS is being run between Edge and Core Devices in the same POP
and Cell-Mode MPLS id being run between the Core Routers across Different POPs
Cell-Mode TE Tunnel is established between POPs to prefer a Physical Path per ISP
Preference and all MPLS VPN Traffic is sent down that Tunnel Using Autoroute by default
by manipulating the Autoroute Metric.Also the TE Tunnel have a dynamic path option adeed
other than explicit for backup in event of core link failure
We need to manually configure Route leaking on Core routers from level-2 to level-1
Also the edge routers are not wide-metrics capable and hence we enable ISIS Metric
Transition on Core Routers
ISP AS used 64513
VRF USed cus1
rd 64513:1
rt 64513:100
IGP is ISP Domain used ISIS with Core Routers and their Loopbacks in Level-2 .
IGP in Custmer AS Used OSPF
PE-CE ROuting Protocol is OSPF
