Hello,
Would like to know if this topology may be good, and also have some support to some concenrs.
our idea is to setup the following network topology. As you can see, both ASR's are redundant and can stand a failure on our providers AS174 (Provider 1 I) or AS89xx ( Provider 2 C ) but not at same time, we can even shut down one of the ASR without losing internet connectivity, so our first option is to connect our clients on 7600, because otherwise we can't connect them to both ASR's.
Configuring BNG on the ASR's to connect there the PPP clients is our plan B ;)
HW taken: 2 ASR9K redundant, 1 ASR1006 to entrance the PPPOE, instead 7600.
ASR9K trident card redundant, A9K-8t-l to contain costs. We have it an re use it. processor will be RSP440.
Main question about the ASR9006 is the 1 million routes limit of the trident card. This way we are limited to maximum-paths=1, what happens during BGP convergence? Do you lost connectivity? This is our main concern
Attached a PDF with NW topology.
Thanks a lot since now for your help.
