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
