RE: [swinog] MPLS VRF source routing (inter-vrf routing)

by Varaillon Jean Christophe

Could NAT be an option?

BUT: somewhen it stops working because of one thousand possible CEF bugs ;-( i have to put "no ip route-cache cef" on the interconnection interface, then it works. some hours later (as already said) it stops working. when i do again "no ip route-cache cef" on the interface it works some other hours. i've tried several IOS for the C7200series and the only half-way working version is the 12.4T (or even 12.3T). so, now the big question to the community: 1) do you see any other working way doing source-routing from one vrf to another vrf? (there's a vrf source routing command, but i think this will really not scale) 2) do you have encountered the same CEF bugs? (i have seen them on 7206, 1841 and 2851 series routers) how cisco tells me to do it: http://www.cisco.com/en/US/products/sw/iosswrel/ps1838/products_feature_ guide09186a0080296409.html i would be glad to get some input from you guys. greetings -steven _______________________________________________ swinog mailing list swinog(a)lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog Disclaimer The information in this e-mail and any attachments is confidential.

AW: [swinog] Skype

by Josh Geisser

Although skype is funny, see online status and have a chat, it's not a real phone-solution. Someone ever did transcontinental calls? 400ms+ rta? The good old ISDN is much better :) And if you dont like fiddeling around with ISDN and swisscom and so on, get yourself a good internet connection (0% packetloss :)) and try one of the SIP providers near you (like http://e-fon.ch). Some of them having quite interesting prices, and if needed, extra-features (like web-based pbx-config, iax trunks, etc).
