Interfaces
-
Support for VLAN rewrite operations on CCC interfaces (MX480 and MX960)—Starting in Junos OS Release 21.2R1, you can configure VLAN rewrite operations on CCC interfaces.
[See Configuring Q-in-Q Tunneling and VLAN Q-in-Q Tunneling and VLAN Translation.]
-
Support for coexistence of source IP hash with consistent hash (MX Series)—Starting in Junos OS Release 21.2R1, source IP hash, which allows the flow from a particular source IP to always be hashed to the same link while load-balancing the flows across multiple paths, supports consistent hash, which prevents the reordering of flows to active paths in an ECMP group when one or more paths fail.
Note:This feature is applicable only to external BGP (EBGP) ECMP paths.
[See Configuring Load Balancing Using Source or Destination IP Only and Configuring Consistent Load Balancing for ECMP Groups.]
- AMS on MPC10E line card (MX240, MX480, and MX960 with MX-SPC3)—Starting in Junos OS Release 21.2R1, we support load balancing and high availability (HA) features on aggregated multiservices (AMS) interfaces for Layer 4 and Layer 7 services such as stateful firewall, intrusion detection service (IDS), and the Traffic Load Balancer (TLB) application.
