Propagate Static Routes into Routing Protocols

A common way to propagate static routes into the various routing protocols is to configure the routes so that the next-hop router is the loopback address (commonly, 127.0.0.1). However, configuring static routes in this way with the JUNOS software (by including a statement such as route address/mask-length next-hop 127.0.0.1) does not propagate the static routes, because the forwarding table ignores static routes whose next-hop router is the loopback address. To propagate IPv4 static routes into the routing protocols, include the discard statement at the [edit routing-options static (defaults | route)] hierarchy level:

[edit routing-options rib inet6.0 static (defaults | route)]

discard; 

To propagate IPv6 static routes into the routing protocols, include the discard statement at the [edit routing-options rib inet6.0 static (defaults | route)] hierarchy level:

[edit routing-options rib inet6.0 static (defaults | route)]

discard; 

In this configuration, you use the discard option instead of reject because discard does not send an ICMP (or ICMPv6) unreachable message for each packet that it drops.
