interface bonding

[Richard Bejtlich]

Thanks to Dmitry's tip on ng_eiface, I'm happy to
report using the following configuration to bond
interfaces with ng_one2many and a virtual interface
ngeth0.

sf2 and sf3 are real interfaces connected to my 10/100
tap.
--
kldload ng_ether
kldload ng_one2many
ifconfig sf2 promisc -arp up
ifconfig sf3 promisc -arp up
ngctl mkpeer . eiface hook ether
ngctl mkpeer ngeth0: one2many lower one
ngctl connect sf2: ngeth0:lower lower many0
ngctl connect sf3: ngeth0:lower lower many1
ifconfig ngeth0 -arp up
--

It works:

bourque# tcpdump -n -i ngeth0 icmp
tcpdump: WARNING: ngeth0: no IPv4 address assigned
tcpdump: listening on ngeth0
13:42:49.322474 86.84.6.72 > 216.239.39.99: icmp: echo
request
13:42:49.340745 216.239.39.99 > 86.84.6.72: icmp: echo
reply

Sincerely,
