I don't think so that one should avoid running routing protocol due to the
fear of BUGS and other things. If we think like that trust me then we will
not be able to run most of the feature set of firewall.
For example ASA support S2S, Remote Access and SSL VPNs so I should avoid to
run two or more type of VPNs together ? The answer is simple NO. Yes some
error or bug occur I will try to solve it or workaround it other wise
calling TAC is the last step.
I don't think so firewall becomes more vulnerable by running routing
protocol. if we think like that then we will be also avoiding running VPN
and CBAC (application firewall) on the routers and also then we will also be
avoiding running CME on the Routers as well.
So no need to worries : )
