How to make the router in running condition.
I just upgraded my cable modem from the Motorola Sufboard 5120 to the DOCSIS 3.0 capable 6120. Provisioned it with Comcast and their "Blast" service (supposedly it caps at 16 down, 2 up).
I had, in the past, used my desktop via N-format wireless (DWA-525 N-format PCI adapter and DIR-655 N-format router) to do a speedtest.net test. I was getting 16 down and 2 up (as advertised). When I switched to the 6120, I did a speedtest.net test again to see what kind of gains, if any, I was getting. Turns out, I was getting 20+ down (nice improvement) and 1/2 Mbps up (a fourth of what I used to be getting?). Called Comcast. They "sent signals" (don't they always?) and claimed that it fixed it. My download speeds increased a smidge (about 22), but my upload speeds were still .5. Called Motorola, they had me do a few things and now I get 1 Mbps up and 27 - 30 down via wireless.
My download speeds are great. I'm content with that. If I hardwire from the cable modem directly to a ****py old laptop, a speedtest.net shows 4 Mbps up. So why do I get such a high upload speed when hardwired (4 Mbps), but a fraction of it (1/4th) when wireless? I'm not using any other devices to sap bandwidth (some are connected -- i.e. another desktop, my Droid phone, etc., but aren't actively pulling packets). And why would it go from 2 up (on my desktop via wireless in the past) to only 1 up (via wireless now) when the setup is the same across the board (as best I recall) other than upgrading my cable modem.
Since I get 4 up when hardwired straight off the cable modem, I assume my DIR-655 is slowing me down somehow. How to pick up the pace a bit? I've already tried the standard "power cycling", etc.
Oh, and the reason I go wireless -- my cable modem and wireless router are in my game room in the basement for my PS3. My desktop computer (and the wife's desktop computer) are two floors directly above it in our "office". Signal strength is "excellent" ... always has been. And again, pretty much everything is the same.

I need to connect site to MPLS provider and run Cisco GETVPN.Problem:I have been browsing Cisco Feature Navigator Tool and to my surprise when I enter "platform:3745" I can't find an image compatible with GET VPN. there is no workaround (image) I can run GET VPN on 3745? I need IP routing (BGP, OSPF) as well.
View 1 Replies View Relatedwe've got a pair of old 3745's that are getting upgraded to new 2911's, and I'm trying to run IOS 15.2 on the new routers to get them most current before going into test and production use.The routers are doing BGP, IPv4, and HSRP, and I'm trying to put one in at a time as to not have to big bang everything at once. I'm putting the one that matters least in first, and basically using the same config as the old one, which was running IOS 11.
I was using "no ip mroute-cache" on ethernet interfaces, and it says that command is deprecated and I should use the MFIB commands instead. Darn if I know what that means, I believe it was set up so the ethernet interfaces had IP multicast fast switching disabled, which was set up by our vendor 10 years ago so I'm not sure if it matters. It would seem logical to me this would have an impact on HSRP and speed of failover. Does this matter, and if so how in the world do I do this with IOS 15.2?The second one is the use of "no fair-queue" on our serial connection for a T1. This command isn't there either, and I'm not sure if I even need to bother on this. It was set up on the old router on a T1 Frame Relay circuit.
There is no special requirements, just need new hardware with some reserve availability. As for now it's 3745 EOL and I assume to use 3945.

I have to replace the 3745 which is our edge router (running (C3745-ADVIPSERVICESK9-M), Version 12.4(23), RELEASE SOFTWARE (fc1)) with (I think) a 3900 (drawing from memory, I haven't actually seen the device yet).In an ideal world, I SHOULD be able to just set term length to "0", do a show run, copy that off to a text file, and then paste it into the new one...

I intend to deploy a voice+data network using some old 3745 and 2811. The network in effect has six 3745 in a hybrid topology at different locations and each having three WIC-2T, one WIC-4T, three NMHDV-2E1. That's pretty much juicing out the maximum from these routers These will serve as my core routers and for access I will be using my 2811s with more VWICs and lesser WIC-2T to give voice and data to subscribers. The 2811s will have links to multiple 3745s. The NMHDV-2E1 will serve for the voice needs at the 3745 locations. All the WAN links will be E1. All my telephones will be on analog voice using traditional EPABX with CEPT/ PRI E1 cards for connecting to the routers. And for data, ethernet ports.Two of the routers will have E1 links to the PSTN and Internet which has to be extended to all my folks. Now, for the tricky part, all my network modules are refurbished stuff from ebay and all the ports will have links on them. I intend to use OSPF with only the backbone area.

View 1 Replies View RelatedHave an ADSL router (887) at a site which has a GRE tunnel to to a 3745.The GRE tunnel is setup with default ip mtu of 1476.If I ping from the 3745 to the ADSL router (or in the reverse direction)with a packet size of 1500 bytes this works fine.However if I ping from a router (R1) that is directly connected to 3745 to the ADSL router with a pkt size of1500 bytes then the first ping succeeds while the subsequent pings fail.Pkt sizes less than or equal to 1476 work okay.Pinging between R1 and the 3745 with a packet size of 1500 bytes works fine.If I set the tunnel ip mtu size to 1500 bytes then it works.This is obviously something to do with fragmentation, but I don't undertsand why itdoesn't work with the default mtu set to 1476.

View 3 Replies View RelatedI have a subnet (vlan 104) working great across a WAN. At site 1, Router A (3745) has the L2TPv3 tunnel configured while Router B (7204) has a routed interface on vlan 104.
The only thing router A is doing is the tunnel, so I'd like put the tunnel on Router B and eliminate Router A.
The trouble is, when I move the configs to Router B, the tunnel comes up, but the far side does not receive traffic over the tunnel.
Router B shows sending and receiving packets (per the 'sh l2tun session all' command). The far end router shows sending packets but receiving 0.
Is it a problem to have both the vlan 104's L2TPv3 xconnect interface and the vlan 104's routed inteface on the SAME router?
I am really new to this and studiying so I know that I am doing something dumb. Anyway, I purchased an ASA 5505 and placed it between my Cable Modem and Cisco 3745 router. The outside interface on the ASA is dhcp, the inside interface is 192.168.100.1. The outside interface of the 3745 is 192.168.100.2 and the inside is 192.168.1.1. The VPN pool is 192.168.200.10 - 192.168.200.10.
Here's are the problems...
1. When I establish a VPN session to the ASA, I can ping and access any resources dierectly connected to the ASA's interfaces and on the ASA's internal 192.168.100.0 network. However, I cannot access any resources behind the 3745. I cannot even ping 192.168.1.1.
2. Although I believe that I sent up split-tunnel, I cannot U-Turn back to the internet once connected to the VPN.
I am having problems accessing our internal network via VPN. We have an ASA at the perimeter that connects to a 3745 router and all of our networks come of that router. I can establish a VPN connection to the ASA but I can’t ping any of our internal host.
The internal network I need to access is 172.18.0.0. When I connect to the ASA I get a dhcp address from a pool created in the ASA, the pool is 172.200.1.x. I can’t ping from the ASA to the connected vpn host and I can’t ping from the host to the ASA ip address or to 3745 connected to it.
ASA config:
group-policy NAMEOFPOLICY internal
group-policy NAMEOFPOLICY attributes
dns-server value 172.18.2.2 172.18.2.23
[Code]....
route inside 172.18.0.0 255.255.0.0 172.18.255.1 1 Route on the 3745 back to the ASA ip route 0.0.0.0 0.0.0.0 172.18.255.2 I can’t see anything on the internal network, I can’t even ping the dns servers and so on.
I am having two small issues....First on my 3745 i get the following message:
*Mar 2 12:13:13.615: IP-EIGRP(Default-IP-Routing-Table:1): Neighbor 192.168.3.1 not on common subnet for FastEthernet0/1
*Mar 2 12:13:25.811: IP-EIGRP(Default-IP-Routing-Table:1): Neighbor 192.168.2.1 not on common subnet for FastEthernet0/1
Second problem is that I have my internet connection going to the 3640 on FE0/0 and it works just fine....I want to change over and have the 3745 be the internet router, but when I configure it, I get no connection.

I've came across a very odd topology to deal with where everything is connected to everything, without proper utilization of VLANs.
- I've an L3 SW and a 3745 RTR at core
- Both are carrying same subnet to an L2 distribution switch that connects server farm within the same subnet (i.e. 1.1.3.x subnet)
- The L2 switch works as a passive switch, hence another network say, 1.1.2.x has been plugged into it as well.
- This L2 switch extends to other switches without configuration of any VLANs or STP and distributes 1.1.3.x network.
Periodically and unexpectedly, the router starts hanging and utilization goes beyond 80%, and there's nothing at all that is observed in "sh proc cpu" to be eating router resources. Its quite difficult to observe the pattern, as its random.
Customer has a pair of Cisco 3745 configured with DLSW+...He is in a technological migration phase so he needs to migrate to new cisco platforms.How can I find out which cisco products (switches, routers) support DLSW+ to replace the 3745s?
View 4 Replies View RelatedMy topologie is to connect IBM Mainframes into a Single Gateway Scenario. All the configurations in the machines are correct, and during a feel period of elapsed time we had the mainframe XCA/line/PU Station (Side DLSW) and the PU from CCU 3745 line (Single Gateway Side) both into ACTIVE state. The problem occured when we tried to INACT and ACT the mainframe VTAM lines; The lines, after this restart operation stayed in PCTD1 all the time. Searching the problem into DLSW's Border Router definitions, we observe that there are two Routers Serial Interfaces defineds with the same SDLC VMAC address (4000.3745.0000). Executing the DEBUG DLSW command was verified that there are the following messages:

My question is, the ocurrence of these two delete group cache for the same Mac Address 4000.3745.1, group 0, means the mistake into maintain defined two Serials Interfaces with the same SDLC VMAC Address ?

I'm working on a new DMVPN configuration with one 3745 at the hub site and a 1941 the spoke. I have internet through gsm for the primary line at the spoke and a dsl line for backup on spoke.I have one tunnel interfaces on both the hub and the spoke.Currently my VPN tunnel is coming up fine , however we are planing to do an ISP failover at spoke side . since in the tunnel interface i can only define one "tunnel source interface" which is gsm cellular interface , i don;t know how to use my another ISP for the same tunnel interface as it will always initiate traffic from gsm.
do i have to create another tunnel interface with same hub site , or do i need another hub as backup? is their any other way to create loopback interface and initiate the traffic from that loopback?
