Cisco WAN :: C4507R+E - Maximum Routes Sup 7E?

Mar 10, 2013

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?

Cisco WAN :: EIGRP 101 - Prefer External Routes Versus Internal Routes?

Apr 8, 2011

Is 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.

Cisco Switching/Routing :: Need IOS Updgrade WS-C4507R

Apr 25, 2012

I have a WS-C4507R-E switch.  The current SW Ver. on it is 12.2(53)SG4-IP-BASE-CRYPTO.  I have been tasked with making sure all of our switches and routers have the most current IOS running on them. 
So, with that, when I look at the software available for download for my particular switch, there are several.  Some of the IOS description makes sense, but not even sure really if I do understand what I am looking at.  How do I know which software package I need to use to upgrade the switch?  This is our core switch..while yes, I would certainly back up the current switch, I would hate to be responsible for taking down the entire network due to a unfortunate misunderstanding of what I thought I read, even is it only last as long as it takes to restore from the back up.

Cisco Switching/Routing :: Replacing C4507R-E With Nexus 5548UP?

Jul 25, 2012

We currently have an environment with a 4507 as the core switch connected to four stacks of 3750e's in the wiring closets. A pair of Nexus 5548UP's also hangs off the 4507, but at the moment more or less dedicated to a certain purpose..The 5548UP's have the L3 daughter card installed.
My question is: Can a pair of Nexus 5548UP's do a C4507's job? Would we be able to decomission the 4507 and replace with the existing 5548UP's + FEXes?

Cisco Switching/Routing :: C4507R+E - How To Disable Radius Messages In Console Mode

I am using radius authentication on C4507R+E with supervisor card 6L-E and IOS 15.0.2(SG1). It works perfectly but all radius messages appear in the console. Radius is very verbose, I can't use console because of the significant number of messages and I am worried about switches performances. I add that all debug commands are disabled.

Cisco Switching/Routing :: Enabling Port Security On C4507R Shuts Down Port

Aug 13, 2012

I'm trying to enable port security on several 4507R's. When I try to configure a range of ports the switch will randomly put 1 or 2 in err-disable.  It's different every time I apply the config to the same group of ports.  However if I do them one at a time it seems to work.  But I really don't want to configure 6 fully populated switches one port at a time.   We also have a lot of 3750's and they gave me no problem using a port range.

Cisco :: BGP Routes Not In Routing Table?

Feb 4, 2013

We 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.

Cisco VPN :: ASA 5510 Not Advertising Routes

Feb 15, 2011

I 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 ( /24). Users can log in fine.
I have enabled EIGRP on the ASA and I have configured the following to be advertised:
1. (default)
2. /24 (dmz network)
3. /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 ( to ping the DMZ interface ( 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.

Cisco VPN :: ASA 8.4(3) Dynamic VPN And Static Routes?

May 20, 2012

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?

Cisco WAN :: Setting Up Routes On ASA 5505?

Dec 12, 2012

I'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


Before I added that last "" 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 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 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, right?

Routes from the network2 to network3 should go through RouterA1-Router1

Cisco WAN :: 2911 With Partial EBGP Routes

Jun 29, 2011

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).

Cisco VPN :: C3660 Passing IP Routes To VPN Clients

May 19, 2013

We've got a fairly plain-vanilla VPN configuration on a C3660 router running IOS 12.3(26) so that our employees can initiate VPN sessions to our office using their Windows or Linux workstations.  In a typical windows L2TP VPN configuration, the default route is set to the VPN server, and no other routes are passed to the clients, which means that if the client disables "use default route" setting, even getting to the office network fails. 
I know there's a way to do this, but I haven't found it yet.  What I want to do is pass local routes to the client so that only those routes transit the VPN, and permit the clients to use their own default routes.

Cisco WAN :: AS1234 View Internal IP Routes

Jan 31, 2013

Is there anyway I can see how many routes are internal to an AS?
So, something like "show ip route in AS1234" where AS1234 is the local AS number. All internal routes within AS1234 are being parsed around via iBGP, but AS1234 has a full BGP table from upstream provides so "show ip route" shows all local and global routes. How can I see all the routes within the local AS only?
