| hi ppl,
can someone tell me, why we create some subinterfaces on Bri0/0 like bri0/0.1, bri0/0.2 and so on. For an ISL Router it s suitable to create subinterfaces, cuz of Frame Tagging, but why for bri ??
Thanks for ur help.
Cheers | |

| Probably you are talking about the 2 B channel BRI0/0:1 BRI0/0:2. Are you sure they are talking about sub-interface because their syntax are so similar? | |
|
| yes u r right.....
damn i forgot that ISDN has 2 Bri
oh God
cheers

| Yep,
BRI = two 64Kilobit B channels and one 16Kilobit D channel for signaling. (2+1)
PRI = twenty three 64Kilobit B channels and one 64Kilobit D channel signaling. (23+1) | |

| Ummm.... ISDN PRI is 23 64kbps B + 1 64kbps D | |

It was a typo, thanks for letting me know, and I edited my message. |
