In ISIS this would have had less happy ending, as you only have 255 LSP numbers, ~1500B each, so after ~370kB or so, you'll run out of space where to put your routes. There are some protection mechanism for this scenario, IOS has 'lsp-full suppress interlevel external' and JunOS has 'prefix-export-limit' Very different to advertise say 1M routes from 1router (won't work) than advertising 1k routes from 1k routers each (no particular reason why it wouldn't work). _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
