[c-nsp] Bandwidth displayed on Tunnel interfaces
Hi all, I've got a few protocol 41 tunnels configured on a few different routers, all for IPv6 only. Some of the tunnels are used for BGP peering with transit providers, and the rest join my PoPs together. If I understand the Cisco documentation correctly, the BW is used exclusively for link metric/cost, but it also shows up in my MRTG graphs and skews the percentage results. Since these tunnels operate on top of the same underlying connection type as the IPv4 infrastructure, I'd like to set the bandwidth manually to the same setting as the interface type the tunnel is connected over (or better yet, set it globally for all tunnel interfaces). AFAICT, doing this won't have any operational impact other than what it would normally have on an IGP (which is fine, because all IGP is over direct Ethernet), and fixing my graphing/statistical applications. Can I get some feedback on whether my thinking is correct? Tunnel bandwidth should be 100Mb: pe2-fibre#sh int tun5 Tunnel5 is up, line protocol is up Hardware is Tunnel Description: IPv6 BGP Tunnel to he.net MTU 1514 bytes, BW 9 Kbit, DLY 50 usec, reliability 255/255, txload 18/255, rxload 163/255 Encapsulation TUNNEL, loopback not set Keepalive not set Tunnel source 208.70.111.131, destination 216.218.229.118 Tunnel protocol/transport IPv6/IP Tunnel TTL 255 Fast tunneling enabled Tunnel transmit bandwidth 8000 (kbps) Tunnel receive bandwidth 8000 (kbps) Steve smime.p7s Description: S/MIME Cryptographic Signature ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
