Accepting Route Updates with Unique Inner VPN Labels in Layer 3 VPNs
For Layer 3 VPNs configured on Juniper Networks routers, Junos OS normally allocates
one inner VPN label for each customer edge (CE)-facing virtual routing and forwarding
(VRF) interface of a provider edge (PE) router. However, other vendors allocate one VPN
label for each route learned over the CE-facing interfaces of a PE router. This practice
increases the number of VPN labels exponentially, which leads to slow system processing
and slow convergence time.
Next-hop chaining (also known as “chained composite next hop”) is a composition
function that concatenates the partial rewrite strings associated with individual next
hops to form a larger rewrite string that is added to a packet. By using this function, the
