Definitely, the 75XX is a jump over the 70XX router platform.  However, it
is very simple to collapse a 7513.  The RSP2 does not have enough 
processing capability to allow economical use of the 11 available slots.

We've been able to collapse several 7513's with less than half of the 
slots filled and heavy tuning by Cisco Engineers.

Now, I am in no way, form, or manner an authoritative Cisco information
source, however, I have heard some rumors which I place fairly strong

1.  Cisco will be releasing a new RSP card soon (RSP4) which doubles
	the performance of the RSP2

2.  You all know about the VIP cards along with 11.2 when all of the bugs
	are removed (especially those nasty memory leaks)

3.  There has been a rumor that some level of load sharing between two
	RSP's will be available some time 2Q or 3Q '97

Again, these are but rumors I've heard.  We've been spending a lot of
our time lately playing with the Bay (Wellfleet) stuff, and they have some
pretty neat stuff coming out (thanks to ANS, any comments, Curt?)

1.  They are working on a 64M version of the ARE card (dual Power PC
	chips working in a full load share environment)

2.  a 256M FRE3 card (dual Power PC's again) that they estimate would
		be completely able to support as many as 300 BGP peers with 45K
		route tables.

3.  Channelized T3 interface, native IP over non-traditional IP media, etc.

Again, mainly all rumors.
