Receiving of routes, which are configured in VRF via BGP or/and OSPF, failed. Theneighbor adjacency is
successfully established, but record of routes in RIB is denied
%ROUTING-W-KERNEL: Can not install route. Reached the maximum number of BGP routes in the RIB
Allocate RIB resource for VRF (0 by default). Do it in VRF configuration mode:
esr(config)# ip vrf <NAME>
esr(config-vrf)# ip protocols ospf max-routes 12000
esr(config-vrf)# ip protocols bgp max-routes 1200000
esr(config-vrf)# end
SSH/Telnet sessions, which go through ESR router, are closing.
Configure transmission of keepalive packets in order to keep session active. Keepalive transmission option is
configured on SSH client, for instance, section 'Connection' for PuTTY client.
It is possible to set timeout before closing inactive TCP sessions (1 hour in example):
esr(config)# ip firewall sessions tcp-estabilished-timeout 3600
Firewall was disabled on interface (ip firewall disable). However access for active sessions from the port was
not closed, according to security zone-pair rules, after including this interface to security zone, removing
from 'ip firewall disable' configuration and applying changes.
Changes in Firewall configuration will be active only for new sessions. The reset of Firewall active sessions
does not occur. You can clear active sessions in firewall, using following command:
esr# clear ip firewall session
LACP does not launch on XG ports of ESR-1000/1200/1500/1700
Port-channel has speed 1000M mode by default. Enable speed 10G mode:
esr(config)# interface port-channel 1
esr(config-port-channel)# speed 10G
How to clear ESR configuration completely and reset it to factory default?
Copy blank configuration in candidate-config and apply it in running-config.
esr# copy system:default-config system:candidate-config
Reset to factory default is similar.
esr# copy system:factory-config system:candidate-config
