also you really should take a look on the topologies i've sent for the
juniper guys about the colorful labeled unicast.... :)

is the tread, just "star it" in your mailer then try the new topologies
that'll arrive soon.... :)

also dig into your mailing and try the previous topologies (3 were there already) also,
one of them was a "red-blue vpns over rsvp-te"

hihi

could someone please take a look on carmen's topology?

thx,

Thanks Csaba! I have a simulation that is more or less working... I have the routes for R1, R3 and R4 but not for R2 I don't know why because I have the same. Anyway, it was enough for today Enjoy your weekend

well the less the more sometimes....

3 ospf processes for 1 bgp per topology seeems a bit overkill...

you need 1 ospf and 1 bgp per router and it'll be dual stack all the way
per tology

have you seeen frederic's validated design? almost the same but with rsvp-te
to have
"traffic engineering" capabilities offloaded to hardware....

right?
I remove them and I got this warning:

info cfgInit.executeSWcommands:cfgInit.java:768 line 105: "neighbor fd01:10::1
update-source loopback10" : % in other vrf

Because fd01:10::1 if the loopback of the neighbor that belongs to
VRF_ATLAS.

it's just the service label (4 bytes) which selects the egress interface &

and comparative in mtu:

vlans = 4 bytes

mpls = 2*4 bytes: the outer target node label, and the inner service label

it's just that you dont have to build parallel infrastructure with 3 parallel
ospfs and bgps,

but a single core

an mp-bgp in vpnv4/vpnv6 over loopbacks

and vrfs with route-target export-imports

and kaboom, you have 3 parallel topologies and you can concentrate on pbr if
mpls-vpn-extranet is not better...

I think so... you enable it in that profile, maybe you can check but it
should have both features enabled.
I have never worked with this MPLS Layer3 VPN, maybe I should take a look

btw why the vlan subinterfaces and not mpls layer3 vpn?

normally bridge-filter (acl to count) could be run in paralell with pbr...

these are disjoint controls so i dont think they cannot coexist:

are you sure that profile have both enabled?

Badddd.
I'm able to do PBR or BRIDGE-FILTER but not both at the same time even with the profile CERN_FLOW that you created the last time for us. Then, in some links we only have 1 VLAN
to use and I would like 3 VRFs (for example AMS -> CHI because they use
sense-o) so my supervisor mentioned that there is one technique call QinQ to
encapsulate VLANs.

someone mentioned p4 stuff? how is your experiment is going?
