摘要:
Novel tools and techniques are described for mitigating data loss during failover in a VPLS multi-homed network. In one aspect, a primary link might be established between a lowest numbered provider edge (“PE”) router in the service provider network and a lowest numbered physical site at customer premises outside the service provider network. A stability site might be established within the service provider network, communicatively coupled to at least the lowest numbered PE router via a primary virtual circuit. The stability site might be designated as the lowest numbered virtual site, which might have a site ID number lower than the lowest numbered physical site. In response to the primary link failing or becoming broken, one or more backup virtual circuits might be established between a plurality of ingress PE routers and a plurality of egress PE routers in the service provider network, without destroying the primary virtual circuit.
