Strange routerboard behavoir
by Paul Julian 02 Feb '15

02 Feb '15

Hi guys, we have a large hotspot site which is doing some funny things and I was just wondering if anybody may have seen similar behaviour before. We have a 5Ghz backhaul network which runs flawlessly, running with a mix of SXT's and Omnitiks from a central AP out to a number of CPE's. Off the back of each CPE we run a 411 with a 2.4Ghz radio in it and an omni antenna, plugged into ether1 on each device. What happens sometimes is that we lose sight of the AP connected to a CPE, we can't ping it, however the AP shows in the neighbours list on the CPE and the Ethernet port shows as running, for all intents and purposes everything looks fine, however when you try to telnet from the CPE to the AP you can't connect, when you try and mac-telnet from the CPE to the AP it disconnects and doesn't work. After a varying period of time the connection just starts working again, the uptime of the AP is normal, i.e. it hasn't lost power or rebooted and everything just works OK....until the next time which could be hours or days, no pattern seems to exist. Has anybody encountered such issues before at all ? I have so far replaced the Ethernet joiner between the radios and also replaced the power pack and POE injectors which feed the radios. Any suggestions would be appreciated. Thanks Paul

BFD + OSPF + ROS and BFD + BGP + ROS

Hi I have asked this question on the forums but got no reply I want to run BFD and OSPF together. I have a few routers that have multiple legs of OSPF, but I can't run BFD on some legs, because I have some legacy cisco equipment that doesn't do BFD (ASA5520 8.5). Can I limit BFD to specific legs of OSPF determined network interface Can I limit BFD support on BGP by specific peers even if I have multiple peers on the same interface, last one can I have multiple BGP + BFD peers on the same interface ???
