Re: Are SW upgrades needed in MPLS core networks?

>Just to be sure, my point here is not where the effective IPv6 performance >suits one needs or not, but wether a router that can forward <amount> Mpps >of IPv4/MPLS packets can also forward the same amount of IPv6 packets per >second. Wouldn't a network with an MPLS core use 6PE to implement IPv6 rather than routing v6 natively in the core? In that case wouldn't the forwarding performance of native v6 be irrelevant? --Michael Dillon

this may be deemed off topic - if so apologies in advance. however i respect many of the opinions i see here so thought i would take a chance and ask. we are a stub network, injesting about 30k emails daily. about a year ago we implemented a spam filtering product. it works well. recently we turned on the knob to enable it to do reverse lookups. only the mild version, a reverse is made on the ptr rr for the ip address sending the email. if it fails the spam filter issues a 421 and closes … [View More]

Fwd: SECURITY: Abuse & upnormal traffic in 207.218.250.181 [ev1.net]

Hello folks, I have found that ev1 just ignores the abuse emails, and doesn't want to handle the DDoS complaints. Can someone from their NSPs to contact me off the list since this abuse isn't being handled by them correctly? They are being the great hoster of the DDoS bots in the little secret IRC servers runs in ev1 network. EV1 isn't making the Internet secured place at all. Now the ddos bots connect to tw1st142.q8hell.org ports 7721 and 5912 Thanks, -J Note: forwarded message attached. … [View More]

Cisco: limit number of DHCP addresses per VC?
by Claydon, Tom 07 Feb '04

07 Feb '04

Question for the list: Cisco introduced a command in 12.3T to limit DHCP leases on ATM unnumbered interfaces (ip dhcp limit lease per interface). This feature works fine on our 7206VXR, but my problem is that this is a global command. The Redback we were using before had us spoiled by allowing us to specify max DHCP leases per ATM VC! We would like to put other ATM VC's on this router that have different DHCP lease requirements. Is there any way of limiting DHCP leases per VC? Cisco TAC said … [View More]
