 |
|
Bear with me and see if this makes sense. I have an ATM OC3 port adapter
interface on a 6509. I have two PVCs off this OC3. It's Verizon ATM
service. I provide connectivity to two separate locations through this
interface. I'm trying to figure out if there's a way for me to somehow
extend one of the PVCs to another router, a 7507 ( have ATM interfaces for
it), in particular. I need to keep the one PVC homed off the 6509, but I
need the other PVC somehow extended to the 7507 because it needs to be
behind a different security enclave and subject to different security
policy. I just don't have the ATM experience/knowledge to know exactly
if/how this can be done. Any advice appreciated. Thanks.

You should be able to terminate the PVC on the 6509 using an
sub-interfaces something like:
int ATM x/0/0
no ip address
logging event subif-link-status
interface ATM x/0/0.10 point-to-point
description PVC #1
bandwidth xxx
ip address
pvc PVC_1 1/10
protocol ip x.x.x.x broadcast
vbr-nrt 1536 1536 1
encapsulation aal5snap
interface ATM x/0/0.20 point-to-point
description PVC #2
bandwidth
ip address
pvc PVC_2 1/20
protocol ip y.y.y.y broadcast
vbr-nrt 1536 1536 1
encapsulation aal5snap
You coul then route the other groups traffic thru the second PVC.
If they want to secure the traffic they they could use GRE& IPSEC to
tunnel their traffic |

These two PVCs are already in production and they're terminated with the
sub-interfaces just like you've described. Take PVC #2 for example. I need
to somehow extend that PVC so it terminates on another router.

You need an ATM switch, like the LS1010 or 8510 inserted ahead of the
6509. One with at least 3 OC3c ports. One for the inbound, two for
the outbound.
You map the one PVC to go out one interface, and the other to go out
the other interface in the switch. No problem.
Cost may be an issue that will make you rethink your desire to do this.
You won't be able to do it with the gear you have now. |

Discuss your issue with your carrier to see what solutions they can
suggest.
Also discuss the approach of you just routing the traffic from 7507 (
without using theri ATM interfaces) to the second PVC. As I indicated
earlier they could create a secure tunnel and have it transported over
your infrastructure. |

Ah, I have an old 5513 with a ls1010 with adequate atm interfaces
that's not doing anything. I'll give that a try. Thanks.
