Good to know it is working for you. As I said (but more detail now), Linux version 2.6.16-2-686 (Debian2.6.16-18) ... (Debian 4.0.3-6) What are the names of your subinterfaces? This may be relevant to my situation:  eth1:1 didn't appear in ifconfig, soI tried the following: $ <mailto:seb at thegw1:/etc/network$>  sudo ifup eth1:1ifup: interface eth1:1 already configured$ <mailto:seb at thegw1:/etc/network$>  sudo ifdown eth1:1SIOCSIFFLAGS: Cannot assign requested address$ <mailto:seb at thegw1:/etc/network$>  sudo ifup eth1:1$ <mailto:seb at thegw1:/etc/network$>  Error : Name or service not knownError : Name or service not knownError : Name or service not knownNow eth1:1 appears in ifconfig and starts working again.  (The samebehaviour applies to eth1:2 BTW.) Maybe I'll try this (virtual interfaces with Quagga) in Fedora... Thanks.

Didn't doenything special compared to normal subinterface configs when deployiongquagga so I think there something else wrong with your config. What linuxare you using? ~peteOn 2/26/07, Seb <sebqu at syntec.co.uk> wrote: Are virtual interfaces supported on Quagga v0.98.3 (on Debian GNU/Linux2.6.16)?  (Zebra, OSPF and BGP) On Zebra, I have this in my config: interface eth1:1  link-detect  ipv6 nd suppress-ra ! show interface shows: Interface eth1:1 is down   index -1 inactive interface If I then do a "no shutdown" on this interface from Zebra, I get: Interface eth1:1 is up, line protocol is up   index -1 inactive interface So it has added "line protocol is up" despite the interface not beingshutdown before.  Now I tried shutting the interface down via Zebra, but itstill said:Interface eth1:1 is up, line protocol is up   index -1 inactive interface I noticed that it had shutdown the interface though.  I tried: # no shutdown Can't up interface Then restarting Quagga and show interface now showed: Interface eth1:1 is down   index -1 inactive interface I still can't unshut it down though. In zebra.log I get this when I try and do a no shutdown: 2007/02/26 12:27:06 ZEBRA: can't set interface flags Am I doing something wrong, or are virtual interfaces just not supported?Or has support been added / fixed since version 0.98.3?Any suggestions?
