Switchover downtime in ASr 903 (RSP1) takes between 2-3 minutes

Alberto Seg
Level 1
Level 1

hello, 

We have a ASR903 router with RSP1 and IOS-XE 03.16.02a.S and we have detected that the switchover between the route proccesor takes between 2-3 minutes of loos of connectivity in all of services in the router. (there are a lot of level 3 services in the router, is MPLS PE router)

Is normal this downtime in the switchover?

We have another ASR903 with IOS-XE 03.15.02.S and the switchover don´t have impact. althoug this other router y for carrier ethernet services, this mean that don´'t have any services of layer 3 except OSPF for management. (this ASR for carrier ethernet have RSP2)

Regards
