Hello All!
I encountered such a problem when using MX480 as the main gateway for the network. This message appears many time in logs after all bgp sessions is up:Dec 13 02:45:03 gw-re0 fpc1 RT: Failed prefix add IPv4 - x.x.x.x (No memory) on FE 0

Googling found a recommendation:
set chassis memory-enhanced route
but in my MX480 i see "Warning: configuration block ignored: unsupported platform (mx480)".
a few questions about this:
1) set chassis route-memory-enhanced - is this the same command?
2) does this apply to all MS-DPC at once?
3) can i upgrade MS-DPC memory physically, as example - replace RAM with large capacity, or replace MS-DPC entirely?
4) if replace MS-DPC - then which card?
p.s. in fpc3
another card is installed - the situation is similar there...
