Object

column r/w TIMETRA-TC-MIBTmnxUrpfCheckMode 
The value of vRtrIfuRPFCheckMode specifies the mode of unicast RPF
check.
              
In 'strict' mode, uRPF checks whether incoming packet has a source
address that matches a prefix in the routing table, and whether the
interface expects to receive a packet with this source address prefix.
              
In 'loose' mode, uRPF checks whether incoming packet has source
address with a corresponding prefix in the routing table, however
'loose' mode does not check whether the interface expects to receive a
packet with a specific source address prefix.
              
In 'strictNoEcmp' mode, when a packet is received on an interface and
the source address matches an ECMP route the packet is dropped by
uRPF. If source address does not match an ECMP route, the behavior is
same as 'strict' mode.
              
This object is valid only when value of vRtrIfuRPFCheckState is set to
'enabled'.

Base type
Enumeration
Type Description
The TmnxUrpfCheckMode is the mode of operation of Unicast Reverse Path
Forwarding (uRPF).
          
A value of 'strict' means that uRPF checks if the incoming packet has
a source address that matches a prefix in the routing table, and if
the interface expects to receive a packet with this source address
prefix.
          
A value of 'loose' means that the uRPF checks if the incoming packet
has a source address with a corresponding prefix in the routing table,
but not if the interface expects to receive a packet with a specific
source address prefix.
          
A value of 'strictNoEcmp' means that the uRPF drops a packet with a
source address that matches an ECMP route and otherwise behaves the
same as in 'strict' mode.
