Re: FW: Getting pretty close to default IPv4 route maximum for 6500/7600routers.

Even if the first numbers were correctly calculated, they don't allow for further deaggregation of already advertised prefixes, which shouldn't be underestimated as the commercial value of each address increases... On 10.06.2014 06:17, Bryan Tong wrote: I botched those numbers. Let me fix.

I botched those numbers. Let me fix. According to this countdown: http://inetcore.com/project/ipv4ec/index_en.html we have 6.41 /8's left. So that is 107,541,955 IPs. CIDR - Prefixes - /20 - 26,255.36 /21 - 52,510.72 /22 - 105,021.44 /23 - 210,042.88 /24 - 420,085.76 My apologie

RE: FW: Getting pretty close to default IPv4 route maximum for 6500/7600routers.

Yep, exactly… the problem is the carving suggested by most kills the fact that MPLS and v4 are pooled, which on a larger network is very nice, especially if using 6PE where each v6 route may need an MPLS route too. From: Bryan Tong [mailto:cont...@nullivex.com] Sent: Monday, June 09, 2014 12:37

Re: FW: Getting pretty close to default IPv4 route maximum for 6500/7600routers.

John, great point! Regardless, shouldn't need more than 626K to make it to v6 and we wont need as many for v6. That was one of the problems that v6 was designed to address. On Mon, Jun 9, 2014 at 1:27 PM, John van Oppen wrote: > It is generally much better to do the following: > > mls cef maxi

FW: Getting pretty close to default IPv4 route maximum for 6500/7600routers.

It is generally much better to do the following: mls cef maximum-routes ipv6 90 mls cef maximum-routes ip-multicast 1 This will leave v4 and mpls in one big pool, puts v6 to something useful for quite a while and steals all of the multicast space which is not really used on most deployments.

Re: Getting pretty close to default IPv4 route maximum for 6500/7600routers.

The IPv6 table will not be as big as the v4 table even after full acceptance. Given that most providers will be advertising a single /32 and then rest will be some /48 routes for multi-homed scenarios. My router looks like this FIB TCAM maximum routes : === Current :- ---

Re: Getting pretty close to default IPv4 route maximum for 6500/7600routers.

Why, in your example, do you bias the split so heavily toward IPv4 that the router won't be able to handle a current full v6 table? I've been using mls cef maximum-routes ip 768 which is probably still a little too liberal for IPv6 FIB TCAM maximum routes : === Current :-
