Hi there,
I'm wondering if someone could point out what I'm doing wrong here? all
my routes are being added to the system main table and not my VRF.
I could swear I had this working 100% (I took my config and added vrf
"vrf0" to each protocol), i then regenerated my config file using my
software, rebooted and its not worked since. I can't seem to find what I
broke.
Here is my interfaces... the t0p0 and t0p1 are ip6gretap's, dummy0 is
just a loopback dummy interface. All are slave to vrf0. lgtm.
4: dummy0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue master
vrf0 state UNKNOWN mode DEFAULT group default qlen 1000
link/ether fe:dc:20:04:15:27 brd ff:ff:ff:ff:ff:ff
5: vrf0: <NOARP,MASTER,UP,LOWER_UP> mtu 65575 qdisc noqueue state UP
mode DEFAULT group default qlen 1000
link/ether 8a:8e:21:3d:c4:c9 brd ff:ff:ff:ff:ff:ff
8: t0p0@e0p0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1430 qdisc fq_codel
master vrf0 state UNKNOWN mode DEFAULT group default qlen 1000
link/ether b2:da:ee:78:04:1f brd ff:ff:ff:ff:ff:ff
9: t0p1@e0p0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1430 qdisc fq_codel
master vrf0 state UNKNOWN mode DEFAULT group default qlen 1000
link/ether fa:61:19:72:65:d8 brd ff:ff:ff:ff:ff:ff
the output from ip rule is this... lgtm.
1000: from all lookup [l3mdev-table]
The routes within the VRF look like this, lgtm ... ip route show vrf vrf0
X/30 dev t0p0 proto kernel scope link src A
Y/30 dev t0p1 proto kernel scope link src B
Z/27 dev dummy0 proto kernel scope link src C
My main routing table looks like this... lgtm, I don't even have the
interfaces or anything configured for them in the main table outside the
VRF.
default via 169.254.1.1 dev e0p0 proto static metric 1000
169.254.1.1 dev e0p0 proto kernel scope link src D metric 256
E dev e0p0 proto kernel metric 256 pref medium
F via fe80::1 dev e0p0 proto static metric 300 pref medium
G via fe80::1 dev e0p0 proto static metric 300 pref medium
fe80::/64 dev e0p0 proto kernel metric 256 pref medium
default via fe80::1 dev e0p0 proto static metric 1000 pref medium
My bird config is below ... I made sure to add vrf "vrf0" to all
protocols. I searched the mailing list and I can't see what I did wrong
here.
OSPF comes up fine, I can ping inside the VRF fine, but all my routes
are being added to the main system table.
I cut out the filters, they're not doing anything interesting. Despite
BGP being mentioned in the config below, I don't have it configured atm.
