Thank you for this clarification. Yeah, I understand that ingress LU performs lookup. I meant the case of MX80. It's actually the case of local switching in MPC1 but with twice as many interfaces. Where it's backplane->ethernet direction in MPC and LU does not do lookups, in MX80 it's built-in-XE->MIC direction and LU must perform lookups. Having said MQ is capable to transfer close to 70 Gigs, in case of small packets the LU limitation comes into play much earlier (when MQ only transfers close to 30 Gigs), doesn't it? -- Pavel _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
