I just don't like the idea of moving towards another platform just for this reason, since I'm very happy with freebsd's performance. There used to be a patch for ECMP, but it was a huge hack. very dirty at best. > Sadly whilst I'd be more than happy to work on this (with or without > funding), I don't have the free time to do so, but I may be able to > eke out spare time to look at patches. Any quick hacks you have in mind that could allow multiple copies of the same route / pfxlen in the freebsd routingtable? Doesn't even need to have metrics in kernel-level, the point of the whole thing (for now) would be to be able to insert an additional route with the same prefix, and delete the previousy set route *afterwards*. Which is what ospfd/zebra would do. Any insights / hacks / other dirty things are very appreciated. For all others following this thread: "we'd be happy to sponsor its development" still is in effect ;) Met vriendelijke groet / With kind regards, Bart Van Kerckhove bart@it-ss.be http://www.it-ss.be - "Solid Solutions for your IT needs" "There are 10 kinds of ppl; those who read binary and those who don't" [-- Attachment #2 --] 0 *H 01 0 + 0 *H 0C0a0 *H 0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA0 051014123755Z 061014123755Z0?1 0 UThawte Freemail Member1 0 *H bart@it-ss.be00 *H 0 [. ڄR>XB4ą p')Y.no2lM-( sE R 6=a01!HalhiT>WW˄ t4 C?1 y-Xl%ı{Gږ *0(0U 0 bart@it-ss.be0 U 0 0 *H 4A8V@L~ W'R,VR̊-]fcm 5 :z#> [HW^-$n3U[p;0Ϊ,] gtw@O )OHrR)FWA0-0 0 *H 01 0 UZA10U Western Cape10U Cape Town10U Thawte Consulting1(0&U Certification Services Division1$0"UThawte Personal Freemail CA1+0) *H personal-freemail@thawte.com0 960101000000Z 201231235959Z01 0 UZA10U Western Cape10U Cape Town10U Thawte Consulting1(0&U Certification Services Division1$0"UThawte Personal Freemail CA1+0) *H personal-freemail@thawte.com00 *H 0 id[qG Qr^}- {߅%u(t:B,c'{K~ ݹΖdnD|Mq @8 x^^v]nz| KU)&j8$jDZڣyZ 00U 00 *H ~Ngb*M`o`Xa&R5\0J bB#dG)ߝ^l`q\yn G (|_#& sC%/u Qkw0?0 0 *H 01 0 UZA10U Western Cape10U Cape Town10U Thawte Consulting1(0&U Certification Services Division1$0"UThawte Personal Freemail CA1+0) *H personal-freemail@thawte.com0 030717000000Z 130716235959Z0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA00 *H 0 Ħ<UsUNʙZ hup [v :aQP 0cZ,p+Z?qV˯< 6$*+w=+>@dקe*TH<a@ dr` 00U 0 0CU <0:08642http://crl.thawte.com/ThawtePersonalFreemailCA.crl0 U 0)U "0 0 10UPrivateLabel2-1380 *H HP . fgCL!6 -6/ P p<ab:~ t%Pb'qW%ݩ9 Oe_N4[5MwV!x!5$ F]_eO100i0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CAa0 + 0 *H 1 *H 0 *H 1 060316213620Z0# *H 1уSީ;'K0[ *H 1N0L0 *H 0*H 0 *H @0+0 *H (0+ 0 *H Yl̄8݅R0@Hp .7Q[?as!},_>>P`~أa@1>U鏰7 ڗExo /1TBr vվG&
