A read-only compliance statement for routers running IGMPv1 [RFC1112] and implementing the MGMD MIB. IGMPv1 routers only support the IPv4 address type.

Non-accessible index objects that only need IPv4 support are:

OBJECT mgmdRouterCacheAddressType SYNTAX InetAddressType { ipv4(1) }

OBJECT mgmdRouterCacheAddress SYNTAX InetAddress (SIZE(4))

OBJECT mgmdRouterInterfaceQuerierType SYNTAX InetAddressType { ipv4(1) }

OBJECT mgmdInverseRouterCacheAddressType SYNTAX InetAddressType { ipv4(1) }
