interface showing large number of broadcasts

Hello I moved router to a different office, We switched from adsl to fiber, I changed the ip and default gateway. Now I am getting constant disconnects from my crypto maps and ping timeouts to this remote router. The external interface shows the following output senko-shz#show interfaces ethernet 0 Ethernet0 is up, line protocol is up Hardware is PQUICC Ethernet, address is (bia ) Description: Connected to Internet Internet address is MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 10BaseT ARP type: ARPA, ARP Timeout 04:00:00 Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters 00:16:23 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/40 (size/max) 5 minute input rate 8000 bits/sec, 6 packets/sec 5 minute output rate 5000 bits/sec, 4 packets/sec 3526 packets input, 642599 bytes, 0 no buffer Received 1905 broadcasts, 0 runts, 0 giants, 0 throttles 5 input errors, 5 CRC, 0 frame, 0 overrun, 0 ignored 0 input packets with dribble condition detected 1648 packets output, 529051 bytes, 0 underruns 0 output errors, 0 collisions, 1 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped out

Can anyone tell me what could be the problem?

i also typed

show ip traffic

ARP statistics: Rcvd: 4632 requests, 3 replies, 0 reverse, 0 other Sent: 6 requests, 4 replies (0 proxy), 0 reverse

It almost looks like i have the wrong subnet mask or something similar right?

I hate to be the only one replying to my self but I got a new error from the same router larger (2004317998) than the UDP packet length (65)

Could it be a denial of serverice attack? how can i avoid this?

Yes, it looks like you have some host(s) with either wrong subnet mask, wrong default gateway (not first hop) or you have some device that is malfunctioning.

That reminds me of similar situation that we had with HP Jetdirect that was configured wrong and it was generating a lot of ARP traffic getting the CPU of the switch (and public buffers) to have a really big problems.

Well, you can alway use a sniffer (like ethereal) to get more info about it...
