Cisco WAN :: How Many IP Routes Does 3825 Support
Jan 23, 2011I want to know the number of routes supported by CISCO3825-HSEC/K9(512MB DRAM).

View 2 RepliesI have a 3825 running c3825-advipservicesk9-mz.124-24.T8. It is configured as an eigrp stub advertising only its connected and static routes. There are three WAN connections using a metro ethernet service. Two are data, one for voice traffic. The primary data connections run to two WAN edge ASR1002 routers.
The primary data connection (Gi0/1.943) is 20 Megs, the secondary data connection (Gi0/1.944) is only 15 Megs. Before the secondary connection was in place I only had routes to our backbone via Gi0/1.943 and everything was working great. Some time after the secondary data connection was turned up the routes to the backbone through Gi0/1.943 disappeared from the eigrp topology table causing all data traffic to flow through the less desirable secondary Gi0/1.944 interface to our backbone.
There is a good eigrp neighbor relationship between the 3825 and the ASR connected to Gi0/1.943, but if I show ip protocols it does not list the ASR as a data source. I know that the ASR is advertising its routes because I can see the updates coming from it if I debug ip eigrp. For some reason they are just not being added to the topology table by the 3825, not even as a feasible successor.
I have shut/no shut the interface multiple times at both ends during troubleshooting and I also reloaded and upgraded the code on the 3825 from 12.4(24)T to 12.4(24)T8. We also contacted the metro ethernet carrier to see if they had a policy that could potentially be blocking the traffic (no). My colleagues and I are just not seeing any feasible reason why these routes are not being added.
How many routes support 7206VXR with NPE-G2?
View 2 Replies View RelatedFor ASR1000 to support 4M routes, RP2 must be used.
1) RP2 need to have 16GB memory in order to support 4M routes?
2) Need to use ESP20/40 together with RP2?
3) If RP2 + ESP10, supporting route table size down to 1M?
4) 4M routes is shared for both IPv4 an IPv6?
5) SIP card will affect route table size?
We are planning to run BGP on our pair of 3560G switch, I would like to know how many bgp routes it can support? it currently running on advance IP service.

I just want to know how many ospf routes a catalyst 3740 support ?The cisco doc or datasheets doesn't answer this clearly. Because there is only a statement "unicast routes"!? Does this means all unicast routes (eigrp, ospf....static)If so, there is a statement for about 10k routes ?
View 3 Replies View RelatedIs there a way in EIGRP to prefer external routes versus internal routes. EIGRP always picks up internal routes as long as they are available, no matter if external routes have better metric. Our Scenario is that we have DMVPN hub and spoke topology running EIGRP 101. The Core routers also on EIGRP 101 prefer EIGRP 101 routes. We have the new MPLS network running BGP and redistributing these BGP routes into EIGRP 101. The core routers prefer EIGRP 101 routes (internal) to redistributed BGP (external) routes.
View 9 Replies View RelatedThe process is IP Input and I'm not really sure how to troubleshoot it. I've read through all the doc's on high cpu load if I shutdown the port that feeds that network, CPU drops to around 30%, bring it back up and it jumps up to 90%+. I've got a policy map on the interface shaping the traffic

I am trying to upgrade the IOS on cisco 3825 from 124-9.T1.bin to 124.24.t6.bin, after I upload the configuration to the CF and verify the file, everything appears fine but when I try to load the new image it fails with following error and falls back to old image :-
System Bootstrap, version 12.3(11r)T2, RELEASE SOFTWARE (fc1)
Readonly ROMMON intializedboot: cannot open "flash:"
an alternate boot helper program is not specified
(monitor variable "BOOTLDR" is not set)
and unable to determine first file in bootflash
loadprog: error - on file open
boot: cannot load "c3825-advsecurityk9-mz.124-24.T6.bin"
Then after few minutes it boot to the Old 12(4).9 ios again.
What are the prerequisites before doing this? I have to upgrade a router this Wednesday evening if there is an opportunity to move it to a code that is more current that the one the client is currently running which is 12.4(25b). I see on the Cisco Support site that after this code, everything moves to 15.
View 5 Replies View RelatedWe have a BGP / OSPF configuration as shown in the topology picture. When the connection towards Internet is taken down, we expect the traffic to be forwarded toward WAN 2 (preferred) or WAN 1. The problem is that the BGP learned routes disappears when the Internet connection is taken down. The IP routing table on R2 only shows internal networks and the networks between R2 and WAN 1 and 2. No routes to internet is shown. We run "show ip bgp neighbors <ip-to-wan-1-router> received-routes" it contain internet routes. And when we run "show ip bgp neighbors <ip-to-wan-1-router> routes" it contains no routes at all.
View 2 Replies View RelatedI have an ASA 5510 that is configured for a remote access VPN
When users login, they are given an address from a locally defined pool (172.16.101.1-254 /24). Users can log in fine.
I have enabled EIGRP on the ASA and I have configured the following to be advertised:
1. 0.0.0.0 (default)
2. 172.16.100.0 /24 (dmz network)
3. 172.16.101.0 /24 (vpn pool)
I have also enabled reverse-route injection.
The problem I am having is that the VPN pool network is not being advertised via EIGRP, but the other networks are.
The other issue I am having is that even though I have created access-lists that allow the inside network (10.0.0.0) to ping the DMZ interface (172.16.101.1) on the ASA, the ASA is not allowing it. I have also created an ACL that allows the DMZ interface to ping inside, but this fails as well.
I am running an ASA with 8.4(3) and am trying to setup a dynamic VPN tunnel. We are having a business reason to establish a VPN tunnel to customers who do not have nailed down IP addresses. Now I found a number of documents that outline the steps involved. It seems the basic steps were to Establish a regular tunnelAdd dynamic crypto mapAssign the dynamic crypto map to the tunnel created under step 1. While this sounds pretty straight forward and simple, while prepping for doing just this I hot a road block while thinking it through. In order for my ASA to put anything into the tunnel it has to have a route to the remote network pointing at my VPN peer at the end of the tunnel. How do I do this in a dynamic tunnel? How do I add a dynamic route so the ASA knows which tunnel to stuff the traffic into? How do I stop the traffic from just being send to the Internet?
View 1 Replies View RelatedI'm trying to set up a Cisco ASA 5505. I'm mainly setting things up through ASDM but I also have console access. Right now while I'm setting it up I have the outside/Vlan2 port attached to my existing network and a laptop connected to the inside/Vlan1 port. More info about that:
interface Vlan1
nameif inside
security-level 100
[Code]....
Before I added that last "0.0.0.0" entry, the ASA would not see anything on the internet. Now I can ping any external IP address from the router's console. However, the laptop I have connected to the 'inside' port still cannot reach any IP address outside the 10.10.153.0 network. Every time I try to add a similar route for the 'inside' interface, I get the following error: "You have another route configured for this network any which has same gateway 10.10.152.1 and same metric 1. You cannot add a duplicate route." I know I'm misunderstanding something here. In order to make devices connected to the 'inside' port connect to the internet, I need to set up a new route that will direct these devices to 10.10.152.1, right?
I'm using a Catalyst 4500 switch (C4507R+E) with Sup 7E. Cisco Datasheet of this switch says that it can learn maximum 256K IPV4 routes. Currently it just learns 10330 ipv4 routes. However when I show platform hardware ip route summary, it seems that the FIB is just free 100K routes as below output:
Entity total used free util%
Entries 260096 10332 249764 3
UC Ipv4 110592 10331 100261 9
unused 147456 147456 0 100
My question is: Can I make use of all 147456 unused routes? Or these ones have to use for any special purpose?
I have a 3825 with a 16 port etherswitch card installed that I'm trying to setup rate-limits on. Interface G0/0 is the connection to the outside world and int g0/1 has a couple of 2950 switches attached to it.
The etherswitch card, f1/0, f1,1 etc has corresponding vlans, 902, 903 etc each with an IP 10.110.1.x, 10.110.2.x and all part of access-group 111. The switches connect on sub-interfaces g0/1.101, g0/1.102 etc and have IP's 10.55.1.x, 10.55.2.x and part of access-group 101.
What i'm trying to achieve is that every port / IP that is on access-group 111 shares 3Mb of bandwidth in/out and access-group 101 shares a separate 3Mb of bandwidth in/out.
I've created two access-lists as follows;
access-list 101 permit ip 10.55.0.0 0.0.255.255 any
access-list 111 permit ip 10.110.0.0 0.0.255.255 any
And on int g0/0 I've created the following rate-limits;
rate-limit input access-group 101 3072000 64000 64000 conform-action transmit exceed-action drop
rate-limit input access-group 111 3072000 64000 64000 conform-action transmit exceed-action drop
rate-limit output access-group 101 3072000 64000 64000 conform-action transmit exceed-action drop
rate-limit output access-group 111 3072000 64000 64000 conform-action transmit exceed-action drop
Now instead of both access-groups having 3Mb each they all seem to be sharing 3Mb! I've tried class-maps and policy-maps but to no avail..
LAN subnet conflicts with WAN subnet. My router is d-link 825 and my cable modem is Cisco EPC-3825. Op system is W7. Everything worked great with an older cable modem (Cisco 3000).

Currently, we manage anti spoofing with a bunch of ACLs, however I'm looking for a more manageable solution.

This is a multi site network. Site A has a Cisco 3825 router and connects to 3 other sites over ISP A and 2 other sites over ISP B. Both ISP A & B provide a layer 2 full mesh network. ISP A provides a 100mb pipe while ISP B provides a 20mb pipe.
File transfers (Windows - CIFS) over ISP A's fiber are fast enough and throughput is good. However, file transfers (Windows - CIFS) over ISP B's fiber are slow, even though latency is good. On the 100MB ISP A pipe, file transfer speeds up to 6 M Bps are achieved. On the ISP B 20MB pipe, speeds up to 300KBps are seen for file transfers.
ISP A connects to an on board gig port on the 3825. ISP B connects to a fast ethernet port on an HWIC-2FE card on the same 3825. Both ports then connect to ISP Switches and then full meshed to remote site Cisco routers. What could be the issue? Why am I facing these issues only with ISP B even though the configs for ISP A and ISP B are the same?

The problem is router hangs out , intenet users suffer slowness , criticle service like telnet doesnt work . the only solution i found is a reload ,not to mention this is core router sitting on campus network edge . and servicing around 1000 users !! approx assuming all users have using internet at same time .
how to check , if memory is not sufficient ?further if any users using utorrent or any thing like that , does it make enormous no of connections form same pc ?
is their any licence requird for IOS IPS ?i prefer to turn this feature on to kill torrents connections ? but i fear crashing of router as no of users are huge !any know bug with glbp , nat with ip voice image C3825-IPVOICE-M VERSION 12.4(24) T4 ???
In my live VPN concentrator at work, my 5520 is showing a static route for each VPN client that is connected to my SSL vpn right now. This kind of confused me because wouldn't only one route to the address pools subnet be needed for my vpn users?

How can you remove these "L" routes in routing table?
I bought the SG300-10 Switch a few days ago and updated it to firmware 1.3.0.59, but i think there's a bug in this firmware. If I go to "IP Configuration" IPv4 Routes" in L3 Mode nothing is displayed. In the log file i see that:
21474773112013-Mar-16 09:51:34Error%HTTP_HTTPS-E-DIAGNOSTICS: ERROR - in <RL_vtLeadTableGet> tag, can not find the table rlInetRoutingDistanceTable in the MIB. 21474775182013-Mar-14 22:39:22Error%HTTP_HTTPS-E-DIAGNOSTICS: ERROR - in <RL_vtLeadTableGet> tag, can not find the table rlInetRoutingDistanceTable in the MIB., aggregated (1)
Reset of the Switch doesn't work.
We have a Cisco 7301 concentrator, well two of them in HSRP configuration. We have multiple VPN's setup on that router (crypto map based). Recently we noticed the following:
- There is one IP address that has hundreds of static routes for some reason
- VPN for this customer is working, but I'm trying to find out why this is happening.
Here is how it looks like: S 0.0.0.0 0xF5FFFF2C [1/0] via "ip-address".There are hundreds of entries for a single IP there.
I am working on a network that has four nodes/Currently I have RIP running in between R1 and R2, and between R3 and R2. These are shared and R1 can access R3 just fine.R3 is running BGP and communicating with R4.R3 can ping everything in R4's network with no difficulty.Currently R3 is not rebroadcasting the BGP routes into RIPv2 as needed.I have tried clearing my BGP session and am still not able to get the BGP routes from R4 to R1.

a customer of us asked if C2911 (to be bought) is ok for partial BGP routes.This is the situation: 2 cisco 2911, each peering with 3 other AS (AS1, AS2, AS3), and maybe, in the future, at a small IXP (AS4, AS5, AS6, AS7).They will accept defaults plus partial routes from upstream AS1, AS2, AS3.When deployed at the IXP they also will accept partial routes from AS4-7.So, is 2911 ok for that configuration?the default route is included in the first row of as-path, isn't it?I have no experience with partial routes, only with full (for our datacenter) and default only (for other customers).
