I am planning to provide a redudnt link to our customer. The setup as below:
One link over wireless while the other link over wired link, I want to make sure that I should maintain the same public IP addresses for the customer therefore, I am looking for L2 failover for my customer.
If the wireless down the customer should migrated to wired and vis versa. I have 7200 CISCO Router as Core.
I 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
!
ip route XX.XX.XX.XX 255.255.255.0 YY.YY.YY.YY track 10ip route XX.XX.XX.XX 255.255.255.0 ZZ..ZZ.ZZ.ZZ 254
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
Primary optical link between CPE and PE, and backup 3G/ADSL link between CPE and PE.I am considering link failure detection on primary link (after which backup link should take over). Which method is the least CPU intesive:
1) BGP protocol between CPE and PE
2) RIP protocol between CPE and PE
3) BFD on static routes on PE
Is there difference in terms of CPU load between above mentioned methods or they are more or less the same?Hardver platforms are sup720 BXL and Cisco 7200 G2.
We have a customer who has a network consisting of two ISPs, one as a primary and the other as a backup. We are trying to create a configuration that would allow the primary link to fail and the secondary link to automatically pick up traffic and begin routing .how to set something like this up. Both routers are non Cisco routers and there for HSRP is out.

I have a two fiber connection from our Central Office(6513) to Remote office (6509). I have a requirement that on the remote office if one of the fiber goes down, the second fiber should work as a failover. I am planning to use SUP720-3B SFP to connect to the CO.
Can I connet one fiber to Sup720-3b G5/1 & another fiber connection to G5/2? or Can I connet one fiber to Sup720-3b G5/1 & another fiber connection to G6/2? I am running EIGRP between sites. Any sample config.

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?)
I have a 7200 router with a 12.2.(46a) IOS and I am trying to activate Netflow on a subinterface. From the documentation of Cisco, I should be able to do it since the ios 12.2.(14)S but the command is unavailable.

I have tried also to enter the command in the subinterface directly but it doesn't recognize it.
We 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.

I 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).

What are the rough figures that a NPE-G2 is able to hold for the BGP routing table?
378475 network entries using 51472600 bytes of memory 378482 path entries using 21194992 bytes of memory 63008/63003 BGP path/bestpath attribute entries using 8065024 bytes of memory BGP using 82975730 total bytes of memory
Are these 3 memories different memory allocated or are they are a sub-set of each other? If a NPE-G2 has 1GB RAM, does it mean that the routing table limit is depending on the RAM availability?
recently i removed the squid cache from the 7200 router so that i could apply the Qos on the router my topology is simple i have 7200 with two working interfaces

1- browsing has the highest priority
2-youtube has the 2nd priority after browsing
3-download & other applications have the 3nd priority.
I have 7200 Router some flows are not forwarded and when i check ""show ip cache flow"" output i found the destination interface is going to Null i checked the access-list it permits these flows.
