Map single IPv6 anycast address on multiple anchor Packet Forwarding Engines

You can assign the same IPv6 anycast address to multiple anchor Packet Forwarding Engines to manage high traffic from CPE to internet. By default, this feature is disabled.You can assign an anycast address only to a single Packet Forwarding Engine and the maximum v4ov6 tunnel scale per Packet Forwarding Engine. This restricts a single anycast address to be used for 150k tunnels. To configure the same source address over multiple tunnel-attributes, use set v4ov6 ipv6-anycast-source-duplication statement at the [edit routing-options dynamic-tunnels] hierarchy level. If v4ov6 packets are fragmented, the fragmented packets get steered to one of the anchor Packet Forwarding Engines for IPv6 reassembly processing. To steer the traffic to the correct anchor, Packet Forwarding Engine needs information about the range of IPv4 prefixes that goes over a particular tunnel. To get the range of IPv4 prefixes that goes over a particular tunnel, use set get-route-range statement at the [edit policy-options policy-statement <policy-name> term <term-name> from route-filter <route-filter-value> <range>] hierarchy level.
