What happened?

Simple configuration

! interface TenGigabitEthernet 1/1 no ip address shutdown ! ipv6 route 2a01:0::0::/64 Vlan 10 2a01::1 ip route 10.0.0.0/24 Vlan 10 10.0.0.1 ! end

gives endless loop with error when loading with CiscoConfParse(PATH, factory=True)

FTOS9 route syntax

ip route [vrf vrf-name] ip-address mask {ip-address | interface [ip- address]} [distance] [name description] [permanent] [tag tag-value] [vrf vrf-name] [weight weight-value]

ipv6 route [vrf vrf-name] ipv6-address prefix-length {ipv6-address | interface | interface ipv6-address} [distance] [name description] [tag value] [permanent] [weight weight-value]
