RSVP-Multipath Configuration

RSVP multipath provides multiple paths to reach the destination. RSVP services (L2 VPN, L3 VPN, LU, mapped route, etc.) can be mapped to RSVP multipath so that traffic is load-balanced. At ingress node the traffic is load-balanced based on the configured hash (L3 src/dest IP/port, L2 src/dst mac, or in-label if intermediate Autonomous segments). Each LSP path within multipath group can provide individual protection for each path (facility, 1-to-1, secondary). Each tunnel path in multipath group cost may vary (can have different hop, with consideration for load-balancing the traffic). Each member can have the backup protection as other multipath member path or outside the multipath member path.
