BPGd filter weirdness

[Bernd]

Hi misc@,

I have defined a group in bgpd.conf like this:
iBGP_one="12.34.56.78"
iBGP_two="12.34.56.79"

group "iBGP_Peers" {
        remote-as       9876
        neighbor $iBGP_one {
                descr           iBGP_one
        }
        neighbor $iBGP_two {
                descr           iBGP_two
        }
        local-address   12.34.56.66
        announce        all
        depend on       em0
}

Now, setting filters using that group does not work; setting filters 
based on the individual neighbor's IP address does work.

allow quick from group iBGP_Peers
# this does NOT work

allow quick from 12.34.56.78
allow quick from 12.34.56.79
# works

Running bgpd -nv -f /etc/bgpd.conf shows

allow quick from group iBGP_Peers

and

allow quick from 12.34.56.78
allow quick from 12.34.56.79

respectively. Where's the difference?

Thanks in advance,

Bernd
