A service provider engineer enabled the BGP next-hop tracking feature and also tuned the OSPF to increase the network convergence in case of network failures.
However, the operator engineer notices that in cases of PE failure, the network convergence is still slow. Which configuration must the operator use to remedy this failure scenario?
