View 2 RepliesWill there be a way sometime in the future to add static IPv6 routes? I have a routed /64 and a routed /48 from a tunnel broker that terminates on my DIR-815, and I want to hang the /48 off of another router that I have attached to my LAN interface(goes to my home lab setup that I use for my job). I could just move the tunnel endpoint to the other router, but I like having IPv6 access for all my other PCs on the LAN segment.

Trying to control capacity utilization for guest users connecting to a 2960 switch. No problem for IPv4 users, but IPv6 is giving me fits. What I've found out by trial and error so far implies that there is just enough IPv6 smarts in a WS-C2960-24TT-L running c2960-lanbasek9-mz.150-1.SE to make it impossible to control IPv6 traffic. Blocking IPv6 would be sufficient short term, but MAC filtering on type 0x86DD does not appear to work either. Here are the results I've gotten so far:
What "works":
* Protocol ipv6 or an IPv6 ACL in a class map.
* Using a class map referencing ipv6 protocol or an ipv6 ACL in a policy map.
* IPv4 inbound filters and policing.
* Blocking of IPv4 traffic by a MAC ACL blocking type 0x0800 (IPv4) - note that the docs explicitly state that MAC filters do NOT filter IP traffic, except for on this box on this release they do.
What does not work:
* Applying a policy map referencing a class map referencing protocol ipv6 or an IPv6 ACL to an interface. The service policy is accepted by the parser, but is not inserted into the running configuration.
* "class-default" in a policy map only matches IPv4 traffic, not all other traffic.
* Blocking of IPv6 traffic by a MAC ACL blocking type 0X86DD. No problem applying the access-group to the interface, it just doesn't do anything.
I am aware that this box is not supposed to support IPv6 other than for multicast, but as implemented, this is a hole an abuser could drive a MAC truck through.
My questions:
Is this situation unique to this particular 2960 switch or SW release (I also tried 12.2(58)SE2) or does it afflict all 2960's running LANbase?
Assuming the answers to the first two question are negative, what is the minimum requirement to get working IPv6 policing in an edge switch?
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.

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.

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?

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?
For ASR1000 to support 4M routes, RP2 must be used.
1) RP2 need to have 16GB memory in order to support 4M routes?

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?

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:

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:

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.
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?

View 3 Replies View RelatedI am trying to set up a pair of 1941 routers in a HA configuration to act as L2L VPN gateways. The active router of the pair should distribute routes to the remote destinations using OSPF to internal routers. The VPN part is working fine and the routers are correctly advertising routes to internal hosts, however my problem is that when an IPsec sessions disconnect, the routes disappear and therefore internal hosts cannot reestablish a connection. If the remote end establishes a connection, the routes appear again and connectivity is restored.
My setup is as follows: (ASA) --> (pvpn01 & pvpn02 HA pair) --> (internet) --> (remote peer)
The other router in the pair has exactly the same config except with different interface IPs. The remote end is configured to talk to the HA address
91.216.255.248.The VPN routers are both running IOS version 15.0(1r)M9.
When I initially boot the routers, the route for 192.168.66.0/24 appears in 'show crypto route', and is advertised to neighboring routers. If I ping an address on that network an SA is established and stays active as long as there is traffic flowing. pvpn02#show crypto route
If I then stop traffic flowing over the tunnel and wait until the IPsec SA lifetime is expired, the route is deleted from the system routing table and therefore not distributed by OSPF. The result is that internal hosts cannot reestablish the tunnel as the other routers have no route to the 192.168.66.0/24 network.
Is this a bug, or is there another way to get the RRI routes to persist on the active router?
Problem: RV042 is not announcing a class C VPN route via RIP to other routers. It announces the gateway public address via rip, but not the VPN route.
I am attempting to use a pair of RV042 as a redundant links between our home office and a branch. The home office and branch is already connected via a T1. Each location also has an additional cable internet connection with public IP address and a cisco 1921 router controlling the traffic.
The 1921 routers are using OSPF to route traffic over the T1 and have RIPv2 enabled to talk to their local respective RV042s. Here is a description of how the network is set up.
MainRouter - cisco 1921
Eth0 - Network is 192.168.41.0/24
IP address is 192.168.41.20
Eth0/1 - Network 10.1.1.1 255.255.255.254
T1 connection to branch router
[code]....
Anyhow I'm thinking a workaround might be to set up a GRE tunnel across those 10.0.X.X subnets to the other side so I can at least dynamically route traffic accross.... Without the RIP routes being announced I don't have automatic failover!
