Provider standard ARP Timeout?
by Jay Nakamura 10 Aug '12

10 Aug '12

Cisco default ARP timeout is 4 hours. Do anyone change that to something shorter in a provider environment for customer with Ethernet connectivity? What is a good value to set it to? Are there any impacts for lowering the timeout? Other than higher CPU util for doing ARP a lot more on the router?

Verizon FiOS - is BGP an option?
by Justin M. Streiner 09 Aug '12

09 Aug '12

All: I realize this might be a bit of a fool's errand, but I'm trying to determine if Verizon will speak BGP with FiOS business customers. Their website is relatively lean on details. Everything that mentions BGP points to VZB services, which does not appear to include FiOS. Looking at the routing table, I do see several non-VZ ASNs downstream of AS19262, so it looks like it might be possible. If that is the case, could anyone lend any insight to get past the "what is BGP?" response that likely awaits from their salescritters? jms

Packets dropped due to ICMP off
by Jim Ray 09 Aug '12

09 Aug '12

Awe, man, don't laugh too hard. Turned out to be problem with Firefox. Safari on iPhone and IE on PC work. I learned something, too, and appreciate the input: tracert using ICMP is not valid test. Not everyone has ping enabled. So, what looks like packet loss at next hop is really ICMP turned off. Sent from my iPhone

UCSF Network Admin??
by Robert Glover 09 Aug '12

09 Aug '12

Hello, Is there anyone with clue from UCSF on-list? Or if someone knows how to put me in contact with them, that would be great. We are not able to query their DNS servers from our network. We've got users not able to access anything UCSF due to this. Thus far, their response has been to manually put DNS entries into our users hosts file, not actually fix the real issue. Thanks, -Robert

next hop packet loss
by Jim Ray 09 Aug '12

09 Aug '12

Good afternoon. I am a newbie to this group, and this post is my first post ever. A friend from another list recommended this group. I have a Time Warner Business Class connection and am unable to reach http://www.checkpoint.com to research product line I wish to carry. I did a trace route and confirmed packets are past my network, Time Warner network and onto next hop where they execute jump to nowhere instruction. Time Warner says it is off their network, and they can't help. I received no reply from above.net next hop. What is the best way to solve this type of problem? Here is the tracert just now (it has been failing for weeks): C:\Documents and Settings\jim.ray>tracert checkpoint.com Tracing route to checkpoint.com [216.200.241.66] over a maximum of 30 hops: 1 52 ms 28 ms 37 ms 10.129.96.1 2 10 ms 12 ms 16 ms ten13-0-0-238.rlghnca-rtr1.nc.rr.com [66.26.32.2 42] 3 16 ms 12 ms 12 ms ae19.rlghncpop-rtr1.southeast.rr.com [24.93.64.0 ] 4 19 ms 23 ms 24 ms 107.14.19.20 5 16 ms 19 ms 19 ms 107.14.19.133 6 28 ms 20 ms 19 ms xe-0-1-1.er2.iad10.us.above.net [64.125.12.61] 7 23 ms 19 ms 19 ms xe-2-0-0.cr2.dca2.us.above.net [64.125.31.209] 8 74 ms 49 ms 56 ms xe-0-2-0.cr2.iah1.us.above.net [64.125.28.50] 9 77 ms 79 ms 79 ms xe-0-3-0.cr2.lax112.us.above.net [64.125.30.50] 10 85 ms 86 ms 86 ms xe-1-0-0.cr2.sjc2.us.above.net [64.125.31.233] 11 84 ms 92 ms 86 ms xe-1-1-0.er2.sjc2.us.above.net [64.125.26.202] 12 86 ms 86 ms 105 ms 64.124.201.230.b709.above.net [64.124.201.230] 13 * * * Request timed out. 14 * * * Request timed out. 15 * * * Request timed out. 16 * * * Request timed out. 17 * * * Request timed out. 18 * * * Request timed out. 19 * * * Request timed out. 20 * * * Request timed out. 21 * * * Request timed out. 22 * * * Request timed out. 23 * * * Request timed out. 24 * * * Request timed out. 25 * * * Request timed out. 26 * * * Request timed out. 27 * * * Request timed out. 28 * * * Request timed out. 29 * * * Request timed out. 30 * * * Request timed out.

I have a server hosted on Bell Canada's network and I saw an outage of about 30 minutes today, but it ONLY affected connections from Verizon's network. This includes my own FIOS connection. I still could connect to the server through Comcast, Level 3 and XO with no problems. Traceroutes from my Verizon IP only got 2 hops, stopping at a philly router and traceroutes back to the same IP from that server got as far as NYC.

Anyone at Bell Canada / Sympatico can tell us what's going on? Our routing table is going nuts with Bell advertising a lot of routes they shouldn't be
