I'm trying to sort out someone else's 800 series router config IOS 12.2 that was just added onto for years and never cleaned up. There are about 10 route map statements near the end. As far as I can tell, only two are being used. Doesn't a route map statment have to be called(referenced) in another statement in order to actually be used such as either under an interface or in a nat statement?

The host IP 84.204.x.x unable to announce through BGP
BGP configuration on Cisco 1841:
!
interface FastEthernet0.1201
encapsulation dot1Q 1201
ip address 172.18.11.1 255.255.255.252
no ip redirects
no ip unreachables
no ip proxy-arp

I am advertising the 172.16.10.0 network from R5 to R1 via EBGP. The problem is that on the Router R1 I see the route 172.16.10.0 whith show ip bgp command but in the show ip route don't appear.I thinked that the problem was SYNCHRONIZATION,so that will activated synchronization on the routers R1 and R4 but don't work. Furthermore the routers R2 and R3 neither receive the route via OSPF.

The problem is that despite the primary line fails, doesn't change the path and continue going by the main route.I have a very similar setup, also with a cisco 877, but with a normal DSL and it works perfectly.I solved the problem by activating a tracking but is slower than the other method.
View 2 Replies View RelatedI need to be able to redirect some HTTP traffic to an Ironport WSA (for now) on a DMZ interface, the initial config I'm trying to test is along the lines of the following (don't have access to the ASA at the moment to cut-and-paste):
access-list 101 deny any any neq www
access-list 101 deny tcp host 10.0.2.2 any
access-list 101 permit tcp any any
route-map proxy-redirect permit 101
match ip address 101
set ip next-hop 10.0.2.2
Unfortunately the ASA does not take the "set ip next-hop" command, I get an invalid input error message and if I at the route map config prompt type "?" only the "metric" and "metric-type" commands are listed as available.
This happens both on 8.2 (ASA5510) and 8.4(2) (ASA5505). Since others are able to make this work, I assume there's something else on the ASA that I have to set to enable this command?
I changed from a Linksys E4200 to a 5505 and when I use trace route, it doesn't return a DNS name for each hop. I can see the hops shown as asterisks. Do I have to add something to inspect for this to work?
View 1 Replies View RelatedMy network has two connections to a third party via links on two seperate ASA , one in location A and one in location B. The link in location A is the primary connection and the other in location B should be used by only two terminals (term1, term2) in location B. ASA are running OSPF and are redistributing static routes as metric-type 1 in OSPF. In order to achive the aforementioned goal, I have configured a route-map on ASA location B, that sets the metric for the route towards the third party to a high value (100). This way, all routers, even those in site B prefer the exit through location A (metric about 24).
I have checked that my routers correctly have the route to the 3rd party through location A, and the OSPF database has records for the network from both locations.In location B, I have configured the following route-map (on 6509)
route-map PREFER-LOCAL-ROUTER permit 10
match ip address XXX
set ip next hop locationB-ASA
int vlanYYYY
ip policy route-map PREFER-LOCAL-ROUTER
[code]....
From the terminals (term1 and term2) I have tried a traceroute towards the 3rd party's subnet, but I don't get any match neither on the access-list nor on the route-map. Unfortunately I have no other way to test that my configuration is correct, since the application on the terminals, that should access the 3rd party network, is not currently running.
I also addedd the statements below to the access-list, because of the test with tracert:
permit icmp host term1 route_to_3rd_party 0.0.255.255
permit icmp host term2 route_to_3rd_party 0.0.255.255
Nothing changed...Is there something wrong with the above config? Is there a chance that there is a problem with the IOS, that simply doesn't show any hits?
I am trying to create a very basic template in compliance manager that checks for interfaces that aren't members of specific VLANs. VLAN 10 being one of them. I want to match interfaces assigned to VLAN 20. According to the documentation I have read, the following range statement should work because 10 falls between 3 and 19:
Submode: interface [#.*Ethernet.*#]
- switchport access vlan [#[3-19]#]
With the preceeding statement, however, interfaces assigned to both VLAN 10 and VLAN 20 are matching the rule. With this specific rule (not a range), only interfaces w/VLAN 20 are processed by the template, which is expected. We actually have numerous VLANs that we want to exclude/include. I only mentioned VLANs 10 and 20 for brevity.
how to debug an ACL I've created on a 4404 WLC, specifically I want to monitor what packets are being denied by the ACL as something that should be working isn't
I've created an explicit deny statement at the end of the ACL and verified that the counter increases each time I try the problem software update.
What I can't work out is how to get the WLC to tell me what packets are being denied by the explicit deny statement, all I can find are 'show acl' commands which just give me the counts.
The equivalent on a router would be debug ip packet acl and adding the log keyword onto an ACE. I suppose I could configure a SPAN session on the WLC uplink to the switch but that seems overkill?
I have the following zebra.conf on my router box "A":
hostname nuclear-router
password password
enable password password
interface eth0
ip address 192.168.2.1/24
multicast
[code]...
eth0 is connected to a switch and contains the 192.168.2.0/24 range, and A is connected to my WRT54GL "B" (with IP 192.168.1.1, containing 192.168.1.0/24 range, DHCP serves IPs above .100) wirelessly. B is connected directly to my DSL modem.
The problem is that when I specify the default route using the interface name, I can't connect to the internet from A or any hosts behind it - I'm always hit with a "no route to host" error. Name lookup and pinging any local host (even in a different range) or the DSL modem works fine - it's only when going beyond the modem that things stop working. However, when I use the IP of B as the gateway, it works fine. I noticed that route output on A when the default route was specified using the interface alone had only an asterisk in the gateway column. I was under the impression that these approaches should be identical in practice, so though I got it working, I'd like to know what I'm misunderstanding (and/or misconfiguring). Why didn't the default route work when specified using just the interface?
All routers and the modem too have RIP (version 2) enabled, and of course the password isn't really the word "password".
I am having a problem w/ my PIX501 w/ "Cisco PIX Firewall Version 6.3(4)", upon issuing the command i get this WARNING, is this normal? because it works perfectly fine in version 7.2(2)..

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 have a NAT/Port Forwarding going on for which I need to deny all traffic except the one mentioned in my ACL/route-map, So, port forwarding from host A to host B, all else, deny. The port forwarding works, but for some reason.

I have a Cisco 819 router and it's the first time I've configured any Cisco product. Starting from scratch, I have managed to get 3G working and the VPN to connect but so far no packets can route down the VPN tunnel (the other side is openswan/shorewall on CentOS5).I've been pawing over lots of guides and forum discussions but seem to be a bit lost. I suspect I'm missing some access-list definitions but don't really know how to go about it. I want the network behind the Cisco 819 (10.x.x.0/20) to be able to access the internet through the interface Cellular 0 but also the VPN remote network (192.y.y.0/24)When I ping from the other (non-cisco) end I see on the Cisco 819.

View 6 Replies View Relateda) one router with two ethernet interfaces (LANs) and a serial interface. The serial interface is connected to the internet, dynamic nat is used for hosts in the two lans. A web server has a private address of 172.168.50.10 and it is being translated to the internet with serial's interface 68.32.x.x (public ip) with static nat. Clients in the internet type the public address to access the web server.
b)Problem: clients inside the LANs cannot access the web server by typing the public address, they use the server's private address instead, this create a problem with DNS static entries in the HOSTS file in the OS. It is a test server and is only available to authenticated users (lock and key ACLs), so no need to make a real DNS record. The entry in the HOSTS file points to the public address.
c)Question: how can a create a route map to change the public address in the HOST file to the private address of the test web server everytime a user in the LANs type the domain name.
I know RD is used to make an IPv4 address unique in an MPLS VPN system.I don't understand why a PE sends the RD when advertises a route via BGP.I thought RD were only local significant. But I made a packet capture and the RD is actually sended inside the MP_REACH_NRLI attribute:
(from packet capture)
Label Stack=19 (bottom) RD=12:1, IPv4=172.16.22.0/24
MP Reach NLRI Route Distinguisher: 12:1
Why the RD is sent? I suppose that the PE receiving the update checks the Route Target Extended Community to know to which VRF associate the update and not the RD.I made a test between PE1 with RD 12:1 and PE2 with RD 13:1 and there was full routes exchanges, the same when both PEs were using the same RD(all this configured in the correct VRFs). The only difference is that PE2 now shows in their corresponding VRF BPG table "Route Distinguisher 13:1".

I have a 2801 with dual ISP connections, and I have configured route-maps to direct voice traffic over ISP1 (working just fine), and I'm attempting send all other traffic over ISP2 (traffic is load-balancing instead). The connection to ISP2 is DHCP, and I have configured a route-map to route this traffic using the 'ip next-hop dynamic dhcp' command, but when I look at the route-map, it states the following: ip next-hop dynamic dhcp - current value is UNKNOWN..Is there something that I need to enable in order to see the next-hop, and properly send traffic over the ISP2 connection?
