Hello guys,
we configured
BDI interfaces
on our ASR 903 and using a
Tengig interface
for bridge domains....
We wonder which speed the
BDI interfaces
use?
Bandwith parameter shows
1000000 Kbit/sec
. but this I think is important for overlaying protocols and has nothing to do with the actual speed right?
How can we check if the BID "uses" the full speed from the
Tengig interface
, anything we need to configure or will the
BDI interfaces
use the full 10Gig?
Config:
interface TenGigabitEthernet0/0/0
description connect wan wansw01 1/4
no ip address
cdp enable
service instance 1 ethernet
encapsulation untagged
l2protocol peer cdp lacp
bridge-domain 1
!
service instance 3207 ethernet
encapsulation dot1q 3207
rewrite ingress tag pop 1 symmetric
bridge-domain 3207
!
!
interface BDI3207
description DC-GWAN-SIG
vrf forwarding gwan
ip address 172.25.82.53 255.255.255.248
!
nekwz3dcrt01#sh int BDI3207
BDI3207 is up, line protocol is up
Hardware is BDI, address is acf5.e628.2d3f (bia acf5.e628.2d3f)
Description: DC-GWAN-SIG
Internet address is 172.25.82.53/29
MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,

Thanks for your feedback

Hello @andreas.fuchs ,

Your understanding is correct the BDI bandwidth value does not cause traffic rate limiting on the physical
interface tengiga
You may want to change the bandwidth under the
interface BDI
just for documentation purposes
Hope to help

can you post
show interface ten 0/0/0

In the absence of QoS policies, the scheduler will default to allocating all the available bandwidth of the parent physical interface to the BDI. If you have more than one BDI, and no QoS policies, all BDIs will contend for the physical interface's available bandwidth.

Thanks guys, just wanted to confirm if my thoughts are correct.
Cheers
