Having a problem with NTP on an 1841 with VRFs. I have configured the following:interface VlanX description NTP interface ip vrf forwarding NTP ip address <ip address>ntp authentication-key 1 md5 blahblahntp authenticatentp source VlanXntp master 2nt...
We have the following topology:Core Router > ---area 0--- > Our WAN router > ---area 301 nssa no-summary--- > Provider WAN RouterWhen I shut the link from the Core Router, our WAN router continues to advertise a default route into the Provider WAN. ...
Scenario - 6509 connected via multiple etherchannels to a number of 3560s, 3750s and 3120s. I changed the etherchannel load-balancing algorithm, at which point the ports that were members of the etherchannel to the 3750Es all dropped out, but none of...
Hi all,I'm trying to establish an IPSEC tunnel between an ASA (remote 3rd party) and my 1841, but the IKE phase 1 is failing to negotiate saying that it cannot find a mutually acceptable policy. As far as either myself or the other engineer can deter...

I saw when I did a bug search earlier, that but it appears to only refer to BGP.Nevertheless I am currently searching for a more recent IOS that will actually fit in the RAM of the 1841s we use.
Nothing unusual - the ports physically go down, then come back roughly one minute later. The etherchannel also goes down (which I suppose is entirely expected since the ports go down), then is restored when the ports return. There are no tracebacks o...
I am not sure why are you using "ah-sha-hmac esp-aes-256"Because the last time I scratch built an IPSEC tunnel on an IOS device was 2002 and apparently I'm still living in the past where AH is in use...That fixed the issue. The ASA at the other end w...
