AI Technical Summary
In large-scale VPN service scenarios, existing technologies assign too many VPN identifiers, causing device capacity to exceed limits, and the allocation method for each next hop poses a routing black hole risk.
By determining whether data plane type identification information exists in the Autonomous System Edge Router (ASBR) based on the packet encapsulation type, decapsulating the packet, and forwarding it using the remote routing table, the number of identifier allocations is reduced. Furthermore, a virtual routing table for forwarding VRF type remote routing table is constructed to reduce device capacity requirements.
This effectively reduces the number of identifiers to be allocated without increasing device capacity, avoiding routing black holes and insufficient device resources, and ensuring the reliability of packet forwarding.
