match vlan traffic

hi there!

I apologise if post already treated. I have a simple problem. How to prioritize vlan traffic “in the middle” of the tunnel.

Let asume issue such as follows:

------eoip-tunnel1                                                  eoip-tunnel1--------
                          Router1--------Router2------Router3                           --->Internet
------VLAN(id=333)                         |                      VLAN(id=333)-------
                                                   |
                                                   |
                                               Router4

On router1 and router2 eoip-tunnel and vlan interfaces bridged.
My issue is on Router2: How to give higher priority (and limit) to traffic passing between routers 1 and 3 instead of router4.

in general, you should not break the VLAN and bridge it with other interfaces.

i think, on router1, you should add vlanid=333 on interface connected to router2, bridge both vlan interfaces. then do it on router2/3.

and then you can limit traffic on different interfaces on router2 =)

3

is that meant that we can repeat that on many routers “at the tunnel” if we replace router2 with a track of routers.

in general we have 4 routers between router1 and router3. the main idea is to garantee some Internet bandwidth to another router/customer behind router1.

4

yep, it is

but… you may try EoIP tunnel between router1 and 3, and bridge vlans with EoIP

5

yes, they bridged. see above

6

hmmm… from your diagram, i thought that eoip comes to router1 from the left, and other eoip comes to router3 from the right =)

well, in your case, why not just prioritize traffic from router1 to router3 and vice versa?

7

yeah, probably diagram does not exlplain good as well. both sites router1 and 3 ends with ethernet ifaces. so, on these interfaces have created vlan, eoip and they bridged at last. customer that have to be prioritized is behind router1, i.e. his out interface attached to a switch with interface on router1. also there are many users on the same switch. at the same time we have many customers/routers attached on a switch with router4. router 4 have also other interfaces, etc…
in one word, we wanna give high priority to a customer/router atached on a switch “behind” router1. is it possible to garantee some (Internet) bandwidth with that web of connections on router2 and “in the midle” of the tunnel.

i hope i was more clear

why not just prioritize traffic from router1 to router3 and vice versa?

it is if you do not have other eoip between r1 and r3. if you have any - you should ‘break’ it to have control of the passing traffic. so in that case you better use bridged vlan interfaces, as i mentioned in the begnning

9

but what is goin’ on “in the middle of the tunnel”… as i wrote above actually we have several routers @router2 … a tones of connections etc… practically user prioritized @router3, but in case of some overload ping times increases, even packet loss etc.

10

so is that enought? and what about router2… can we garantee some bandwidth there?

11

just mark packets from r1 to r3 and from r3 to r1, and in queues set limit-at = guaranteed bandwidth

12

may I say MPLS …

13

does ros support mpls? v3?

14

i’m affraid, no. already discussed in the forum before.

thank you for your posts, guis, obviously best decision of the issue is vlan with eoip, bridged.

thank you very nuch again
