Routing

I'm trying to configure a Cisco 1941 to connect to multiple Amazon VPC instances. Each VPC instance brings up 2 x IPsec over GRE tunnels with BGP in to the EC2 cloud and enables flat extension of the corporate LAN. Basically. you can spin up EC2 inst...

Hello all, I'm trying to implement service policy on our ipsec tunnels on ASR1001. Version: asr1001-universalk9.03.13.01.S.154-3.S1-ext.bin Here is the typical Tunnel configuration: interface Tunnel100 ip address 172.x.x.x 255.255.255.252 ip mtu ...

While labbing today I've ran into some strange behavior with BGP communities/route-map processing. Basically the objective was from R9, send a community for the 172.30.79.0/27 route out to R7 to 65100:90 AND send a community for the 172.30.89.0/27 ro...

Good afternoon all, I have labbed a L2TPv3 Ethernet Pseudowire topology to try and learn more about the differences between L2TPv3 vs L2 VPN o/MPLS etc and now that I have it labbed and working I can see how it would scale from a SP point of view i.e...

Hi, I have a local network with multiple VLANs and I would like to have a DR site where I could use those same VLANs. I will have only Internet connectivity to DR site so my question is how do i make existing VLANs available on DR side? GRE, IPsec in...

Hi there folks - it's been a while since i've been on here so i'm hoping the level of technical expertise is still upto the previous high levels. I have a problem with a C887VA-K9 that i've been scratching my head over for some time now.  The router ...

Hello everyone,Can anybody tell me if IPX protocol is supported by the IOS that comes with the CISCO2921 routers? I am about to replace my CISCO2821 router by a CISCO2921 router, but I just don't want to spend the money if the new 29xx series routers...

From the ASR920 datasheet, I see it has listed 20,000 IPV4 routes. I'm assuming that this is a problem if I wanted a full BGP table from an upstream ISP? Kinda disappointing since I could do that on a NPE400! Thanks.

I'm currently tasked at my job to help rebuild and increase the strength of our core. i work for an ISP and we are upgrading from 1GB backhaul to 10gig and we need to upgrade everything from bgp routers to Fiber switches as we want to run Fiber to al...

Hi,I have two different isp's with different bandwidth.In this networks are advertised by eigrp protocol & packets are sending ip load sharing per packets configuration. 1.Isp-1 having a 10Mbps bandwidth & Isp-2 having a 2Mbps bandwidthIn this scenar...

We have two sites, with fibre broadband at both sites (40/10Mbps). One site has a UC500 that hosts 6 phones and 2 phones connect remotely via IPSec VPN on a Cisco 887VA router.I am trying to apply QoS for the voice traffic for best performance over V...

Hello Guy's I am looking into the possibility of providing L2 services over a pair of ASR 1002X. however I am having some issues. On Router 2 I am able to see the MAC address of  SiteA's Vlan 901 interface ( E8B7.4869.CCBF). This suggests that packet...
