Dec 12, 2012I am having some issues with creating an ACL for my gateway router.I want to block external access to my network 192.168.1.0/24 from internet so i set up the ACL on the WAN port of my 7200 router asI am using named extened access list -
{
deny ip any 192.168.1.0 0.0.0.255 log
permit ip any any

Linksys Wireless Router :: E4200 Not Recognizing Hard Drive (Seagate 7200)?
Jul 2, 2012I have a E4200 router, and I had previously plugged in a small external hard drive just to test the functionality. The router seemed to recognize the storage, and the computers on the network could see it as a shared drive. Now I have plugged in a Seagate 7200 internal hard drive inside a Rocketfish enclosure, but the router is not recognizing anything. I just upgraded the firmware to 1.0.04, but there was no change. Are there problems using an enclosure rather than just plugging in an external hard drive?

1. Is is supported/possible to provide multicast within a vrf on 7200's?(From initial investigations, it appears to be)
2. Is it possible to only enable mutilcast in a vrf(i.e. not globally)?
3. Any recommended guides/best pratices?(Googling has revealed nothing really that is similiar to what we want to do)4. What are the potential ramifications?(Resource overhead, Security implications, anything else?)

Cisco WAN :: 7200 - Dynamic Failover With IP SLA On IOS 12?
Mar 7, 2011I am trying to configure a dynamic failover with IP SLA on a Cisco 7200 using 12.2(33) IOS. I would like to have something similar as the following configuration:
ip sla monitor 1type echo protocol ipIcmpEcho x.x.x.xfrequency 3ip sla monitor schedule 1 life forever start-time now!!track 10 rtr 1 reachability
access-list 101 permit icmp any host X.X.X.X echo!route-map LOCAL_POL permit 10 match ip address 101 set ip next-hop Y.Y.Y.Y set interface Null0!ip local policy route-map LOCAL_POL

My questions are the following
Question 1: What is the equivalent of ip sla monitor in 12.3 for dynamic failover with IPsla Should I used
ip sla ethernet-monitor 1 type echo domain name ?
or
ip sla 1 path echo X.X.X.X or ethernet mpid echo domain name or icmp-echo time out 1000 frequency 3 threhsold 2
I do not know if I have to used ethernet-monitor or ip sla. What is the domain name and the mpid associated to the ethernet-monitor ip sla.In the case where I have to used ip sla 1, shoud I used a path-echo, ethernet mpdi or icmp-echo for dynamic failover
Question 2: In 12.3, what is the equivalent to ip sla monitor schedule 1 life forever start-time now.I have found thec command ip sla schedule 1 start now but it does not seems that we could configure the duration.
Question 3: Should I also enable ip sla responder

Cisco WAN :: 7200 / 2921 With VTI IPsec
May 20, 2013We have a Cisco 7204 G1 running c7200-advipservicesk9-mz.122-33.SRE7.bin and we're having a lot of difficulties getting a VTI working to a Cisco 2921 with adv. security. I've ruled out that the 2921 is at fault by successfully establishing a VTI to another 2921 and a 7200 running a different IOS release.
We see the tunnel come up, but when I sent a ping from the 2921 to the 7204 there isn't a reply. When I look at the results on the 7204 from a 'sh crypto engine connection active', I see the decrypt counters increase, but I don't see the Encrypt counters increase as it's trying to reply to the ping. I'm not sure if this is because there is an issue with the encryption or whether there might be a more fundamental issue with the router not replying to the pings.
I've tried the following IOS releases (c7200-advipservicesk9-mz.122-33.SRE7 & c7200-advipservicesk9-mz.122-33.SRE6) and they all behave the same way - this makes me think it might be a config issue rather than and IOS bug which is what I first thought. c7200-advipservicesk9-mz.122-33.SRE7.bin.

Cisco WAN :: BGP Peering Causes 7200 To Crash?
Apr 10, 2012I have two 7204VXR with NPE-G2 and 1Gb of ram. One router has 2 eBGP peers and the other has 3. The routers receive all internet routes from the 5 peers and send 2 internal routes. There is an iBGP peering between both routers. On all peers I have a route-map to send only our routes.
All was working fine since a couple of months when I suddenly saw an increase of memory on one of the router (router B), 1 hour later the memory was 100% and router crash and reboot. The other router (router A) with the same hardware capacity, same ram and same amount of routes was working good. After router B restart, I shut all eBGP peering on it, keeping only iBGP with router A, ram used was the same as router A (about 50% used) but CPU was about 30% used by process Router BGP whereas router A which has active traffic and active eBGP is only 20% and bgp process i almost 0%. Restarting peers one by one on router B cause the same issue, increase of memory then crash, even with only one peer.
What I suspected :
- A peer on router B but I can't isolate one because the problem appears with each taken one by one
- Not enough memory, but router A has the same number of routes and don't have any problem
- IOS version ? same on both 12.4.(15)T1
- Why process router BGP use 30% on router B when all eBGP peers are shut except iBGP and no traffic pass.
- A routing loop but I only send internal routes to peers and only have one iBGP session with no sync nor redistribution with an IGP
Of course I can't run any debu ip bgp on routers as the number of routes is very large (300K).
