ICMP, ping, and traceroute ALGs for MS-MICs and MS-MPCs

Junos OS extension-provider packages that are preinstalled and preconfigured on the MS-MIC and MS-MPC offer support for ping, traceroute, and ICMP ALGs in a consistent manner that is identical to the support that the uKernel service provides. Parity and uniformity of support is established for these ALGs between MS-MICs/MS-MPCs and the uKernel service.ICMP ALGs, ping ALGs, and traceroute ALGs were not entirely supported on MX Series routers with MS-MICs and MS-MPCs in comparison with the uKernel service that enables Network Address Translation (NAT) with stateful firewall (SFW) on the uKernel PIC. Supportwas available for handling of ICMP error response packets that match any existing flow in the opposite direction and NAT processing of ICMP packets with NAT processing of ping packets.
