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.

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.

I am running ASR1002 with latest XE IOS version asr1000rp1-adventerprisek9.03.02.01.S.151-1.S1.bin configuration bellow

I also get this message when configuring tacacs. I looked for "new" cli but no luck:LAB-ASR1002(config)#tacacs-server host 2.2.2.2 This cli will be deprecated soon. Use new server cli

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

I'm trying to create a route-map for an EIGRP Distribute list on a N7K, the goal is to not advertise a 10.0.0.0/8 and 172.31.30.20/32 networks out a link to a remote site while permitting all other traffic to the internet (default). I configured the ACL/route-maps below and applied them outbound on the N7K interface but no subnets at all are being received on the remote site router.
ip access-list DENY_10.0.0.0
10 permit ip any 10.244.244.20/30 <<--WAN interface network
20 deny ip any 10.0.0.0/8
25 deny ip any 172.31.30.20/32
30 permit ip any any
[code]....

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.

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

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?

I would like to know how long a route would maintain its community tag when it traverses ***?Basically, a route is tagged 100:1000 when exiting AS100, and then accepted into AS200. AS200 will not modify the tag. Would AS200 export the route to AS300 with the same 100:1000 tag?

I have a XSR-1805 (Version 7.5.0.0) enterasys router here. Got SNMP server to work successfully. The thing is that I couldn't make the router restrict a range of address allowed to use a community. Only 10.1.0.13 is allowed to use SNMP in this case.

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.

I'm getting an "ACL does not match proxy IDs" error that I'm not able to troubleshoot, googled this with a lot of results, tried some; but nothing applied.I have setup 2 tunnels, 1/one from a pix 515e (office) to an ASA 5505 (hosted server) for my guys to access the hosted server2/A second one from the ASA 5505 to my client's firewall so that its equipments can reach the hosted server and from the hosted server reach the equipments.Both tunnels are working fine, my issue comes when I'm trying to join my clients equipments from my office, ie cascading the tunnels.
This is the first time I'm trying to cascade some tunnels, no issues with other vpns I have been building.I'm joining the configuration of the pix and the asa and an extract of the syslogs showing the error, any obvious error I haven't seen!

This is happening to me to multiple computers on my domain. When it happens i can only log in as a local user or if I unplug the network cable, log in and then re-connect the networkThe time on all these machines is correct within at least 1 minute but still it's throwing off this error. When reading about this problem I see many fixes that all relate to how to sych the time on the PC.

On the laptop, the info bar is on the left side, the website tabs on the top, this shifts the other computers screenview down and to the right, it also cuts off the right side and bottom, with still leaving space on the right side and bottom. The pointer on the lap top does not line up with the desktop, because the screen is shifted, but only a portion of the screen is visible anyway. I used the same password and log in on both computers, don't know if they have to be different.There is full a screen option at the top right, but this causes the top tabs and info buttons on the left side to go black.

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.

The switch does not support these Cisco IOS router ACL-related features: # •Non-IP protocol ACLs (see Table 26-1) or bridge-group ACLs
how we would match ICMP traffic then?

We have an HQ site with a 2811 (w/ADVSECURITYK9-M) acting as the firewall. We currently have 1 ASA5505 that has an established ipsec l2l VPN. I'm trying to connect a 2nd ASA, but I've noticed I can only add 1 cryptomap to the outside interface. A show ver shows 1 Virtual Private Network Module... Surely that doesn't mean only 1 VPN?Do I use one crypto map, and add a second 'set peer' & 'match address' inside the crypto map itself?

I've Cisco7609-S with IOS 12.2(33)SRC2 met an issue is that "show ip route x.x.x.x" and "show ip cef x.x.x.x" shown next-hop is not actual switched next-hop.
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.
