Difficulties to Overcome

Previous design requirements

Existing 3rd party vendor in Core Network

1

2

New design needed to inherit all

restrictions from old solution

Topology and IGP metric already

defined in old design

Existing services transport

requirements needed to be “translated”

into new design

Interoperability with Cisco features

not present on Huawei N40Ex16

platform

New design required to cover also

existing Cisco equipment

Solution

IGP Tuning according to current network requirements

BFD to speed up failure detection and shorten convergence time

IGP

MPLS TE

Interoperability

MPLS TE Tunnels with dynamic paths calculation based on IGP metrics

TE Affinity and SRLG features to influence TE Tunnel paths

Auto TE FRR as protection mechanism

LDP over TE as the solution to transport MPLS VPN traffic

Remote LDP peering on NE40E to allow proper cooperation with Cisco LDP Protection feature

Asynchronous BFD sessions on NE40E to use fastest possible BFD timers on Cisco routers
