Cisco Infrastructure :: C3825 / Police Route And Match Community-list

Aug 20, 2012

I have a C3825, and have been using standard ACLs and a PBR to route certain HTTP traffic via an alternative default gateway:

route-map RTRMAP-OfficeLAN permit 10
match ip address RTRMAP-OfficeLAN-toADSL
set ip next-hop x.x.x.x
 
This is working absolutely fine, and as expected, all traffic matching the ACL is being sent to x.x.x.x However, we have recently expanded our network, and I am now receiving various networks via BGP from various sources.  All BGP incoming via iBGP is tagged in communities:
 
Community (expanded) access list 100
permit 37xxx:100
Community (expanded) access list 200
permit 37xxx:200
Community (expanded) access list 300
permit 37xxx:300

[code].....
 
All communities are also matching prefixes when executing either 'sh ip bgp community 37xxx:100' or 'sh ip bgp community-list 100' What I am trying to achieve, is create an EXCEPTION for the policy route.  Traffic matching the community lists, must be forwarded based on the routers routing table, whilst traffic maching the ACL, must be sent via the policy route...
 
route-map RTRMAP-OfficeLAN permit 5
match community 100 200 300 400 500
!
route-map RTRMAP-OfficeLAN permit 10
match ip address RTRMAP-OfficeLAN-toADSL
set ip next-hop x.x.x.x
 
My logic dictates to me that the above should work, but looking at the route-map, I get matches on seq 5 and pacets are exiting the route-map as expected (first matched).  However no traffic that does NOT match community 100,200,300,400 or 500 and that DOES match the RTRMAP-OfficeLAN-toADSL never matches.
 
The counters on the route-map for seq 5 is increasing, but no counters are increasing at seq 10..  It's almost as if seq 5 is matching all traffic.

Cisco :: C6500 - Create SNMP For Couple Of Servers / Access List For Separate Community

Jun 4, 2013

On C6500 series I have to create a separate community to send a SNMP trafic for a couple of gig interfaces.The user that will collect these informations has a Monitoring server and is only interested in monitoring traffic on those link and maybe pps.
 
I understood to create a an ACL pointing to his IP of the server, and that create a community and associate this access list with that community. Those commands I have, but I need to send the user the MIBs or other relevant info on how to collect and forbid everything else but thos interfaces.Do I need to give the SNMP HOST command and associate with this community after that.

Cisco Infrastructure :: 871 NAT List Getting Hit For Traffic From WAN IP

Oct 29, 2007

I have an 871 setup at home with a fairly basic configuration (NAT, Firewall, EasyVPN, Wireless).  What I've noticed is that for traffic going from the WAN interface (FastEthernet4), it seems to be hitting the ACL in place for NAT.  My config: [Code] .......
 
Where 76.22.98.39 is the dynamic IP address from the cable provider.  If the traffic isn't passing through the router, why is it trying to NAT it?

IOS Version is 12.4(6)T9

Cisco Switching/Routing :: Create A Route-map For An EIGRP Distribute List On A N7K?

Cisco Infrastructure :: Route Internet Traffic To Different Gateway Using 3560G Switch

May 24, 2011

My issue: I have installed a firewall within my network.  Currently all my clients default gateway defaults to GW:192.168.1.1. I would like all my internet traffic to route to the firewall ip 192.168.1.30.  My Primary switch ip is 192.168.1.10, which is a 3560G running 12.2(25)SEE2 IPBASE-M.
 
My main problem is, I do not have access to the gateway, so I am trying to route internet traffic from within my switch to the firewall.  I have already tried Route-Map, but seems this version of the OS does not support. I have already tried Policy-Map, but same as above. I have also tried IP ROUT command, but it did not work either.
 
And remember, I would like to perform the routing from the switch, because I do not have access to the default gateway which is a router to perform forward internet traffic to the firewall.

Cisco WAN :: 4900 - Outbound QOS Police Configuration

Jan 12, 2011

I need to attach a QOS policy to a layer 2 WAN interface between two sites.  This is actually an extended LAN circuit with 500Mb/s of allocated bandwidth.    The interfaces are Gigabit so I want to make sure I don't attempt to transmit traffic faster than 500Mb/s.  What is the best way to implement an outbound QOS policy that sets the minimum and maximum speed to be the same? This policy will be implemented on a 4900M with the 20 port GigE module

Cisco WAN :: 886VA-K9 / Qos / ATM / VoIP - Where To Rate-limit / Police

Apr 8, 2013

Setup:

Cisco 886VA-K9
Cisco IOS Software, C880 Software (C880DATA-UNIVERSALK9-M), Version 15.2(4)M3, RELEASE SOFTWARE (fc2)
 
This router has two VLAN's on one Ehternet interface

VLAN1: data
VLAN2: voice
 
The WAN connection is a regular DSL line with PPP.

Modem FW  Version:      120306_1254-4.02L.03.B2pvC035j.d23j
Modem PHY Version:      B2pvC035j.d23j
 
Output of show interface brief:

Interface                  IP-Address      OK? Method Status                Protocol
ATM0                       unassigned      YES NVRAM  up                    up
BRI0                       unassigned      YES NVRAM  administratively down down
BRI0:1                     unassigned      YES unset  administratively down down

[code]....
 
We all know you can't manage data traffic on the internet since your not in control of both sides of the link. So only queuing would not be a good practice IMHO. I was thinking on just rate-limit or police data-traffic so Voice always has bandwidth available when needed. I've did tried to rate-limit on the ATM0 interface, but no luck. Voice was still very bad.
 
My question is: where to rate-limit the data traffic? On the VLAN interface, the ATM interface, DIALER interface?

Cisco Firewall :: 5510 Trace-route / Antispoofing On Not Default Route

Jun 24, 2011

I've enabled antispoof on all interfaces on asa 5510.If you start a traceroute to a network on the default route, everything works, since replies comes to an interface with route 0.0.0.0/0 defined.If you start a tracer route to a network that is NOT on the default route (let's assume coporate MPLS), you only get response from first carrier router, the other are discarded because of anti spoof violation.
 
I have ICMP inspection and icmp-error inspection enabled.

Auto-Configuration IPv4 Does Not Match Up

I live in a shared house, and I am the only one who has been experiencing issues connecting to the internet. I have to ask a housemate to reset the server, as this is the only thing that works.

When I am unable to connect, and I use command ipconfig, the following appears: Autoconfiguration IPv4 169.254.23.29 On the occasions when I am connected, the following appears in its place: IPv4 IP Address: 192.168.0.2

One tip that I came across was to check the box (Wireless Network properties, Connection tab) for "Connect even if the network is not broadcasting". I had hoped this simple solution would assist, but to no avail.

Cisco WAN :: 7609-s Switching And Routing Path Not Match

For example, "show ip route 192.168.1.1" and "show ip cef 192.168.1.1" shown correct next-hop is 10.1.1.1, but the traffic destine to 192.168.1.1 actually not through 10.1.1.1, but always through the default route next-hop. Everything works normal after rebooted the router. Suppose it should caused by a bug? BTW, my Cisco7609 is runing BGP with ISP which received about 10K routes.
