[j-nsp] ERX and OSPF advertising

[Kim Onnel]

Hello,

we have an ERX that is terminating the PPP sessions of around 10k users, so
we have like 10k directly connected routes in the routing table, when we
advertise them to the gateway,

we do that with the summary-address command, before that we used
redistribution of connected subnets using a route-map that supress /32, but
we were advised to use the summ-add becasue the route-map will kell the box,
what we're seeing is self-reloading and processing problems on the ERX, is
there any known issue around this, ospf on Junose, whats the preferred way
to do it ?

Regards

ERX#sh run | b router ospf
