MPLS

Hello together,in our MPLS Core we use IS-IS as Routing Protocol between P- and PE- Router. And we use mBGP for VPN based Routing (vrf) between the PE Routers.At the begining everything works fine. But now it seems that the convergence times between ...

PE1-P1-P2-P3-P4-PE2if we know that the MTU in one of the backbone link srunning mpls is smaller than of ther others. then we want to check the MTU workable on this MPLS cloud,then we ping from PE1 with different packet size and DF set to PE2, then sh...

CE1-CE2-PE1-P-P-PE2-CE3-CE3For OSPF superbackbone:From CE2 perspective, PE1 is a ABRFrom provider network perspective, PE1 and PE2 is a ASBR.But for Provider network, how they see CE2?and Do CE1(in other area) still see PE1 as a ABR?

Dear all, Is this possible?ie one E1, having 2 subinterfaces, running FR encap.s0/0.1 for L3VPNs0/0.2 for L2VPNrgds,--shahrin

Dear all,I've MGX 8850 [ with PXM-1E (with 8 E3) and RPM-PR (NPE400) processor ] .....It's acting as an ATM edge-LSR in our cell-mode MPLS network(This network is based on MGX 8850 with RPM-PR acting as ATM edge-LSRs and the BPX 8600 with LSC 7200 ac...

Hi everyone,Just wondering if any lower end Cisco models including the 2500 series or lower models are capable of running MPLS as customer edge (CE) devices. A quick search on CCO for IOS releases that support MPLS fails to list anything lower than 2...

dear all,refer diagram below: PE A -- P A -----CORE CLOUD ----- P B ---- PE B | | RR C RR DPE A and P A located remotely. P B and PE B are at inside the...

Hi all,need some advice here ..1) for QoS, which one better, configure inside CE or PE2) Can we do QoS based on time/date. ie end of the month or after 6 pm, e-mail become silver ..other than that, e-mail traffic is precendence 0. And also bandwidth ...

Does the 7300 currently support MPLS TE, either in the PXF path or software processed?

I have a problem that my PA-A3-OC3MM ATM Subinterfaces status is ALWAYS ( up line protocol up) even if it has no PVC's, is it the normal status or what?!

Hi,I think the P-routers are not able to generate an icmp "packet too big" back to the client of a vrf. So the PMTU-Discovery will not work, right?So must the mtu be the same in the whole mpls cloud ??What about carrier to carrier vpn? Must the carri...

Hello,Two MPLS/VPN questions:1) If using OSPF as the IGP on a MPLS/VPN network, what is the recommendation, using single-area or can i use a multiple-area topology? 2) Are there any limitations about number of VRFs on a PE-router? or the routes on a ...

Hello the following URL provide the latest feature about inter-as MPLS/VPN which is worth discussing:http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120limit/120s/120s24/fsiasl24.htm#1034865 I have some confusion about the...

Hello:We have a legal requirement that oblige us to keep confidentiality in our internal IP network (there are scenarios in which ES have no way to encrypt the sensitive data). We are evolving to a MPLS backbone with PE in each PoP of our company and...

Hi, We are trying to configure a PIX firewall to connect differents VPNs on a MPLS enviroment and we have a problem when we use more than one firewall.With one FW all works fine, but with two or more in some situation we can have recursive routing an...
