Hi *,
I'm having some troubles while trying to make a multilink connection to
my ISP with multiple BRI interfaces.
Here is what I have:
CISCO 2600
8 BRI module (NM-8B-S/T)
IOS 12.1(4)
2 NT1 boxes ( = 2 ISDN lines)
I would like to use the 2 ISDN lines to make a 4 B-channels connection
to the Internet (my ISP allows me to make a 16 B-channels connection).
My isp is using
Ascend MAX TNT nases.
I can get the 4 B-channels to be connected to the Internet *BUT* I only
have a 128Kbits/sec bandwidth then. When I do a 'sh ppp multilink' I get
this:
Router#sh ppp multilink
Virtual-Access2, bundle name is 00c0.7b8e.51c4
Dialer interface is Dialer0
1 lost fragments, 1 reordered, 0 unassigned
0 discarded, 0 lost received, 1/255 load
0x8 received sequence, 0x0 sent sequence
Member links: 2 (max not set, min not set)
BRI1/1:2
BRI1/0:2
Virtual-Access1, bundle name is 00c0.7b8c.9829
Dialer interface is Dialer0
1 lost fragments, 1 reordered, 0 unassigned
0 discarded, 0 lost received, 23/255 load
0x542 received sequence, 0x9DC sent sequence
Member links: 2 (max not set, min not set)
BRI1/1:1
BRI1/0:1
I assume that having two Virtual-Access bundles is *NOT* a good thing.
Another thing not too funny is that I loose my Internet routing when the
4 B-channels are connected to my ISP
Here is the config:
Router#wr t
