Enabling Source Routing

Starting in Junos OS Release 8.2 for IPv6 and Junos OS Release 8.5 for IPv4, source routing is disabled by default on J Series Services Routers , M Series Multiservice Edge Routers, MX Series Ethernet Services Routers, T Series Core Routers, and on EX Series switches. To enable source routing, include the source-routing statement:

Note: We recommend that you not use source routing.

source-routing {(ip | ipv6);}
