What is theoretical and practical approach to configure bgp??

Cisco WAN :: Configuration Script Stored On 2811 Router?

Nov 20, 2011

I have several Cisco 2811 ISR Routers that are functioning as CallManager MGCP voice gateways.  These routers have prtial PRI's attached to them which I realize are not supported by Cisco CallManager using MGCP.  The problem is that whenever the router gets rebooted, the configuration under Controller T1 ends up with the improper PRI Timeslots command and I have to go in and manually change it. Solution:  I have developed smal text files for each router that contains all of the commends needed to get the chnage accomplished (you have to shut down things and remove lines elsewhere to be able to change the PRI Timeslots) and I just telnet to the router and cut and paste the commands into the router.However, I would like to store those files on the router in such a way that I could telenet to the router and then either somehow display the file and then copy/paste it in or possible have a file that could be run to make the changes.  That way I could do the job quickly fram anyplace I could telnet to the router and not have to have the text files on the local machine.

Cisco WAN :: Loading Configuration From Flash Card In 2811 Router?

Jun 6, 2011

have remote routers boot and load a config from the flash card. It seems this is possible if the Flash Class is A, according to the Cisco web site using the
boot config flash:<Config file>
where <Config file> is the file on the flash.
Although this can be applied on 2811 routers, they fail to load the file on the flash card. I've since found that this router type has a Class C flash. So the question is, can either:
Is there a similar process for other classes of Flash cards, specifically Class C?
The router flash be set as a Class A to support this functionality,
The preferred resolution for this would be the first as there are many remote routers installed a diverse and difficult locations to visit, should a format/rebuild of the flash fail for some reason.
don't ask to list the output of a show boot or show bootvar, neither of these commands work. The Startup/Running config lists the boot config line.

On VLAN one I have an IP address of and on VLAN 531 I have an IP Address of, now what I can do is this... I can.. from a workstation on the segment, ping and one server on that segment that has an IP address of, which is fine, but what I really want to be able to do is ping our email server which is on a segment and I cannot. Any commands on what I would need to do to make this work as I would like the segment to ping any other part of my LAN of my choosing.

Cisco Switching/Routing :: 2811 With 16 Port Switch Module Configuration?

May 12, 2013

I have a laptop with a single physical NIC which I have used the advanced management tools to create two virtual NICs (say vlan 10 and vlan 20) and both are on the same subnet (say 192.168.4.x). One NIC is for normal TCP/IP traffic and one is for broadcast/multicast traffic (I have some custom software that requires this to be the case and works fine on an older laptops with built-in physical NIC and PCMCIA XIRCOM NIC). The dual NIC laptop communicates with a dual NIC server via a Cisco 2811 router (which has a 16 port switch module at the back) and has vlans set up so.
What I want is for the single NIC laptop (with two virtual NICs) to be able to also communicate with the server. Basically, one NIC is for normal traffic and one is for multicast/broadcast traffic. All three machines need to be able to talk to each other using the NIC for normal traffic and both laptops must be able to receive broadcasts from the server. What is the best way to configure the router to handle the trunking/tagging? Most configuration documentation I read has two complete subnets for the two virtual NICs. Note that all three machines use static IPs and are part of a workgroup so no DNS and domain servers etc.

Cisco WAN :: Config PPPoE In Router 2811?

May 13, 2013

I get stuck in one case. One of my customer has two FTTH lines. I have to config PPPoE in routers. In one line I config succesfully, but one line never up. I call to ISP they ask me to config extactly VLAN id 10 in the physical subinterface. But in subinterface there is no command "pppoe-client dial-pool-number". I check the old modem FTTH, they also config VLAN 10 in Wan interface. I tell ISP why we have the same two FTTHs, but two differrent config ways. ISP says because the two line run in two different infrastructure, two different devices. I don't know how to do now? stay in customer side or ISP side. Here is my PPPoE config:
interface FastEthernet0/0
no ip address
duplex auto

Cisco WAN :: 2811 / Connection Between Two Vlans On Same Router?

Mar 21, 2013

We have two 2811 router with configured interfaces:

interface FastEthernet0/0.380 encapsulation dot1Q 380 ip address no snmp trap link-status crypto map clientmap!
interface FastEthernet0/0.382 encapsulation dot1Q 382 ip address no snmp trap link-status
interface Vlan1 ip address ip nat inside ip virtual-reassembly
ip route
ip route
interface FastEthernet0/0.197 encapsulation dot1Q 197 ip address ip nat inside ip virtual-reassembly no cdp enable
interface Vlan1 ip address ip nat inside ip virtual-reassembly ip tcp adjust-mss 1452 
So my case is: computer from router1's network can ping (router2 -FastEthernet0/0.197 )computer from router2 network can ping (router1- FastEthernet0/0.380),but can't ping (router1- FastEthernet0/0.382).

How can i connect vlan 380 and vlan382.I want the three vlan to see each other.Is this happen with IRB or not?

Cisco Firewall :: DMZ Setup Using 2811 Router

Aug 11, 2011

I am pretty new to the configuration of a DMZ and I have the task of setting one up.I have a Cisco 2811 Router running Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(24)T1, RELEASE SOFTWARE (fc3), 2 FE interfaces.One FE is connected to the WAN, with a loop back interface configured with the public IP for Internet access in the office.The other FE has 2 sub interfaces configured, one for data and the other for voice traffic.Users within the office are configured to use the data VLAN to access the internet through the WAN.
Now we are setting up some new services and we require to have DMZs setup.I want to setup 3 zones now that the different servers would reside in. How can i achieve this using the existing infrastructure I have?I have an idea to create more subinterfaces and assign them to the zones, but I am still not sure how this would play out. I have been on this for the whole day and unable to make significant progress.
