What is the purpose VPN label?As we know, in the MPLS VPN, the following mechanisms:RD - used to distinguish between overlapping routesRT - used to determine the VRF in which to send the route.But why need a VPN label?
View 11 RepliesI work in a facility where not everyone communicates very well. Everyone seems to have there own method of labeling ethernet cables. We have several hubs (actually it is a cage with a patch panel and a cabinet with several switches containing over 200 ports) in this facility. The roof is supported by columns and the columns are number 1-35 from south to north and A-W from east to west. So the hubs are easily idientiyable by the column number that they are close to, but this is where the standard ends. Some people use the patch panel and port of the patch panel, some people use the server stack number and the port. What is the proper way to label these. Linking a website demonstrating this standard s I can print it off and share with others would be great.

View 2 Replies View RelatedI have a remote site that has an AP running in H-REAP mode which connects over our MPLS cloud to a WLC, which has one interface on the "inside" network and one on our DMZ. The remote AP in H-REAP mode currently only runs our Guest SSID, but now I need to established an isolated VLAN.
Two of the hosts on this isolated VLAN, which is need to support some conference room devices, need to run on wireless and communicate with two devices on the same VLAN that are hard-wired to the switch.
Getting the wireless devices to connect remotely is easy enough by setting up an SSID that uses an IP subnet which one of the WLC's interfaces actually connects to...but can I do that for a completely remote IP subnet (i.e. one that the WLC does NOT physically connect to?). I'm not sure and I'm wondering whether that's the purpose of the "Remote LAN" feature...which is a very new feature.

Currently running ROMMON from S (Gold) region
Is this alright? Is the Gold region like a default region where ROMMON is always installed. And are F1 and F2 just storage partitions that are available to hold backup copies of the ROMMON? From what I read, it sounds like I can copy ROMMON images to F1 and F2, either the same version as the Gold region or different versions. Is that correct? Why would I want to copy different ROMMON versions to F1 and F2?
I have a Dell R300 server and it does not have a separate DRAC card. When the system POSTs I see it shows something about DRAC and it even gets an IP address. But I can't do anything (ping, web, telnet, etc) with that IP address.So basically what is the point of the basic DRAC without buying the full DRAC card? Just a placeholder?

System image file is "flash0:c2900-universalk9-mz.SPA.151-4.M2.bin
I need to have the source port gig0/0 and destination port gig0/1. There is something about the gig port enumeration (slot/port#) that makes the command rejected. It is self explanatory:
#sh ip int brie
Interface IP-Address OK? Method Status Protocol
Embedded-Service-Engine0/0 unassigned YES NVRAM administratively down down
GigabitEthernet0/0 xxx.xxx.xxx.xxx YES NVRAM up up
GigabitEthernet0/1 unassigned YES NVRAM up up
Serial0/0/0:0 unassigned YES unset up up
[code]....
It doesn't matter what slot or port number I use, it is always rejected. The command is rejected for Both destination and source gig interfaces. I tried a wide variety of slot/port numbers. To my best understanding the complete port names are: GigabitEthernet0/0 and GigabitEthernet0/1, so why does it think there has to be another digit after 0/0 or 0/1? Does it have anything to do with the Embedded-Service-Engine0/0 being administratively down?
i two 5550 firewall set up for redundance purpose . in failover we define two different ip add one for primary and one for secondary .interface Ethernet0/0 nameif outside security-level 0 ip address xxxx.0.0.0.1 255.255.255.0 standby xxxx.0.0.2!interface Ethernet1/0 nameif inside security-level 100 ip address 10.0.0.12 255.255.255.0 standby 10.0.0.11.default gateway for host will be 10.0.0.12 (primary fw address) however in case of failover , the secondary fw will be up with ip address that was assigned for primary .in this case the secondary ip add 10.0.0.11 is actually nerver used? similarly do i need to have two public ip address for outside (one for primary and one for secondary ) ? or in case if primary fails the secondary comes onlie and take the ip of primary fw . hence i only need to purchase just one ip address.

View 5 Replies View RelatedJust like to ask first your inputs about the MTUs needed on our proposed setup. We currently have a large internal network composed of several metro ethernet links. We have different carriers and we all know that they do not always provide L1 connectivity. They sometimes do Q-in-Q or EoMPLS or other technologies that would hide their internal network and appear as a point-to-point ME circuit to customers.
We are planning to create our own MPLS network for our clients so we don't have to leak their networks inside ours and we are trying to avoid the overhead of GRE/IPSEC since we'll be adding a lot of client networks and the overhead is not reasonable. So we just thought of MPLS-VPN to at least reduce the overhead and we don't have to purchase a lot of network devices.
With that said, what is the safest thing to ask the carriers and what settings should i put in our network devices. I am still confused with the differences of MTU, IP MTU, and MPLS MTU.
We also have one circuit running 802.1q instead of using routed-port on the switch. Is 802.1q supported in LDP?
Our internal network is comprised of 6500 switches with Sup720 and Gigabit linecards and we are planning to use 3900 routers as PEs. We all hooked up our ME circuits across the 6500 switches.
tell me the IOS (c2600-???) needed to be able to do MPLS on the 2621 XM router?

View 4 Replies View RelatedRecently i purchased Cisco 861-K9 router for my head office.
I have 2 offices (1 is head-office & other is Branch.). i have MPLS Connectivity between 2 offices.
i used 861-K9 WAN port for MPLS Connection.
My question is "is it possible to use the FastEthernet Port of 861-K9 router for connecting the internet Link ?"
I've got a 6509-E in the lab at the moment for some pre-deployment testing, however I don't seem to be able to enable MPLS on a select interface.
router#conf t
router(config)# interface gi1/48
router(config-if)#mpls ip
router(config)#
As you can see after I enter the "MPLS IP" command it simply backs out of interface level configuration back to global exec, and naturally the MPLS command doesn't show in configuration for that interface.
I'm running a SUP720-3BXL with WS-X6748-GE-TX line cards with the DFC upgrade (WS-F6700-3BXL).

i wanted to know if i can and when i will be able to run the nexus 7000 as a Fully MPLS PE router (L2VPN, L3VPN etc..) ?
the interfeces need to be 10Gbps so i need to use the 8 ports & the 32 ports M1 modules.
I have done a bunch of research in trying to re-use an old card/router for testing our new MPLS link. I have a 45m DS3 and was wondering if the PA-MC-T3= card will work UN-channelized. I have tried the "no channelized" command under the controller to no avail. I believe that the card only works for channelized T1's.

View 1 Replies View RelatedI have few inter-AS and Hub & Spoke MPLS L3VPNs up and running but, all of them uses plain IPv4 on the PE-to-CE connecting interfaces for switching the L3VPN customer traffic. While, this is ok to route traffic between customer sites over a ISP backbone using the VRF and MP-BGP/LDP configurations which does the MPLS forwarding in the ISP backbone, i would like to know, how to enable MPLS forwarding on the PE-CE links as well to make it MPLS right from CE1 - PE1 - P - PE2 - CE2 all the way for the VPN traffic.
This way, even the last mile access to CE devices will be an MPLS link over a Ethernet PHY so that, the traffic originating from CE1 to CE 2 will be carried on a MPLS tagged Ethernet frame instead of IPoEthernet frame.
In HQ , we have cisco ASA 5520 . there is a data line which supplied by ISP for MPLS-VPN service with branch office. branch offices also have a data line which r supplied by ISP. And now, I want the branch office to access resource from HQ without site to site vpn configuration( because we don't have ASA or any device to configure L2L VPN) . so, I need to configure the hq firewall to allow the branch office accessing the resource at hq without any restriction.

I had them directly connected with a /30 bit network in the office with a T-Berd plugged in both 0/0 T1 controllers and this config was working, reconfigured them with their LAN IP's and put them on location and now the CEM0/0 interface comes up on both, but the T1 controller comes up and then goes right back down (10 SES) - they can ping each other on loopback and lan interfaces.
View 3 Replies View RelatedWe have Cisco 1921 routers that a provider is using for MPLS. They have it configured so that all internet trafic is passed to an internal ip address that is our proxy server. However, they are pushing all of the routing rules down to the workstation which is causing the local route tables to grow to be massive in a very short time.For example, the second I ping a website, the ip address is resolved and then the route is added for the source ip address with the default gateway of the proxy server.I would have thought that all the rules would have been handled by the router and let it keep the table entries.
